pH value from 0 (sour) to 14 (basic alkaline)

pH value is showing if a liquid is sour or basic alkaline [web01]. A sour liquid for example is dissolving food faster or is attacking metals so they become rusty. A basic liquid is eliminating dirt (like washing powder).

Mostly the liquid is a mixed one, also a chemical solution [web01].

<pH value depends on the quantity of carbon dioxide ions (CO2) [this is the sour element] and depends on hydrogen carbonate ions (HCO3-) [this is the basic alkaline element].> [web11]
(original in German: <Der pH-Wert hängt ab von der Menge an Kohlendioxid (CO2) [das saure Element] und Hydrogenkarbonat-Ionen (HCO3-) [das basische Element].> [web11])
This scheme is going from 0 to 14 points. pH7 is neutral:
  • pH value under 7 (<7) = sour [web16] respectively this is a sour chemical solution [web18]
  • pH value of 7 is neutral (e.g. pure water) [web16] or a neutral chemical solution [web18]
  • pH value over 7 (>7) = alkaline (basic) [web16] respectively can be a basic alkaline solution [web18].

The item of pH

<The item [pH] is derived from Latin "potentia hydrogenii" (= power of hydrogen) and is indicating the hydrogen ion concentration in g per liter. [...] Hydrogen ion concentration in a liquid indicates if the liquid is sour, basic alkaline or neutral. [...] When acids or bases are dissolved in water then they are giving hydrogen ions by dissociation and are therefore changing pH value.> [web07]
(original in German: <Der Begriff  [pH] leitet sich vom lateinischen „potentia hydrogenii“ (=die Kraft/Stärke des Wasserstoffs) ab und gibt die Wasserstoffionenkonzentration in g/Liter an. [...] Die Wasserstoffionenkonzentration einer Flüssigkeit gibt an, ob sie sauer, basisch oder neutral ist.  [...] Werden Säuren oder Basen in Wasser gelöst, geben diese durch Dissoziation Wasserstoffionen ab und verändern dadurch den pH-Wert.> [web07]

<Scale of pH values is limited by the solubility of acids and bases in water. With very high or very low pH values and in concentrated salt solutions not the concentrations are decisive for the pH value but the activities of the ions are decisive. The activities do not depend directly from the ion concentrations.> [web01]
(original in German: <Die pH-Skala wird nur begrenzt durch die Löslichkeiten von Säuren oder Basen in Wasser. Bei sehr hohen oder sehr niedrigen pH-Werten und in konzentrierten Salzlösungen sind nicht die Konzentrationen für den pH-Wert entscheidend, sondern die Aktivitäten der Ionen. Aktivitäten sind von den Ionenkonzentrationen nicht linear abhängig.> [web01]

Responsible for pH value in the body are the lungs (supply of hydrogen), kidneys and the liver (responsible for excretion of toxics). [web16,web17]

Technical terms: alkalosis - acidosis

An acidosis is a sour state respectively an overacidification. An alkalosis is a too basic alkaline state [web11].

In the blood the pH value is 7.35 to 7.45 [web01]. In the blood a pH value under 7.37 is rated as an acidosis and higher as 7.45 is rated as an alkalosis [web11].

In urine and saliva a pH7 is rated as neutral. There are more tolerances concerning sour pH values depending from the author.

pH values in food have an influence to the pH value in the urine and in saliva. But pH value in the blood is always buffered between 7.35 and 7.45 when the person is healthy [web01].

Additionally one has to see the difference how acid or basic the food is and if they FORM acids or basics - this is an important DIFFERENCE. So what is important is what the food is FORMING: forming acids or basics (conclusion Palomino).

Examples of pH values

Here are some examples of pH values of substances and food:

Battery acid <1 - gastric acid (sober) 1.0-1.5 - lemon 2.4 - Cola 2.0-3.0 - vinegar 2.5 - juice of acid cherries (Prunus cerasus subsp. acida) 2.7 - orange and apple juice 3.5 - wine 4.0 sour milk 4.5 - beer 4.5-5.0 - acid rain > 5.0 - coffee 5.0 - tea 5.5 [black] - skin surface of the human 5.5 - rain (natural precipitation) 5.6 - mineral water [with carbonic acid] 6.0 - milk 6.5 - water (depending on hardness) 6.0-8.5 - human saliva 6.5-7.4 - pure water 7.0 - blood 7.4 - seawater 7.5-8.4 - pancreatic juice (intestinal juice) 8.3 - soap 9.0-10.0 - household ammonia 11.5 - bleacher 12.5 - concrete 12.6 - 13.5-14 sodium hydroxide solution [web01]

Examples of substances forming acids in the human body

Be aware that concerning food it's not so important how acid the food is, but it's important what effect it has in your body FORMING acids or basics.

Here is food forming much acid
-- meat, above all pork
-- milk products (cheese, yogurt etc.)
-- white flour products
-- industrially produced pastry products
-- industrially produced noodle products
-- industrial sugar
-- mineral water with carbonic acid
-- lemonades
-- coffee
-- industrially proceeded fruit juices
-- sweets and chocolates
-- instant meals [web18].


Some pH values of the human body
-- normal soap: considerably basic alkaline [web01]
-- amniotic fluid: pH8,5 [web02]
-- sperm: basic alkaline [web01]
-- arterial blood: pH7,35-7,45 [web01]
-- vagina: sour [web01]
-- skin of the human body: slightly sour about pH5.5 [web01]
-- today's washing lotions (with water, glycerin, sodium chloride, sodium thiosulfate, sodium hydrogen carbonate, distearates, tensides): pH5
[web01]

pH value in the human blood is always the same pH7.35-7.45
[web01] with the best working immune system [web18].

pH values of organs and body liquids

Table: pH values of organs and body liquids
Body liquid, organ etc. normal pH value
Blood about pH7,4 (pH7,36–7,44; depending from the definition also 7,37–7,43)
Urine normally slightly sour, depending from the food can also be alkaline (pH4,5–7,9)
Stomach pH1–4
Bile pH6,5–8,2
Stool pH7
Saliva pH5,5–7,8
Skin about pH5,5 ("acid mantle")
Saliva pH4,5 (protection effect against infections by antibacterial effect)
Vagina (above all the lower 2/3s) pH4–5
Secretion of cervix pH7–8,5
Sperm pH7–7,8
Body cells
Normally there are more hydrogen ions in the body than in the blood - body cells have normally a pH value of 7,0–7,3.

[web16]

pH value in the urine is variable: it's the indicator for the food indicating health dangers.
[web05]

pH value of the skin: about pH5.5

<Human skin is slightly sour, pH
≈ 5.5. Acid mantle is a protection from germs.> [web01]
(original in German: <Die Haut des Menschen ist leicht sauer, pH ≈ 5,5. Der Säuremantel ist ein Schutz vor Krankheitserregern.> [web01])
Body care has to be basic and then the acid mantle is reinstalling itself again:

original in German:
<Eine naturbalassene, basische Körperpflege mit leicht basischen Werten (pH 7,4), wie sie heute von einigen wenigen Herstellern angeboten wird, ist sehr viel geeigneter für die tägliche Hautpflege, da dieser pH-Wert die Haut nicht austrocknet. [...] Unser Körper ist - aufgrund der extrem hohen Säurebelastung - nicht mehr in der Lage, die anfallenden Säuren über die Nieren oder den Darm auszuleiten, so dass er die Haut zur Hilfe nehmen muss. Aus diesem Grund ist der pH-Wert der Haut auch extrem niedrig. Er liegt im Durchschnitt bei pH 5,5.> [web02]


Translation:
<A natural basic alkaline body care with slightly basic pH values (pH7.4) as it's offered today by some producers is much more appropriate for a daily skin care because these pH values are not drying out the skin. [...] Our body is - because of the high charge of acids - not capable to excrete the acids over the kidneys and intestine so the skin has to be taken as a help. By this reason the pH value of the skin is extremely low. The average is about pH5.5.> [web02]

pH value with soaps and lotions

Soaps are basic and provoke a dry skin. After the body cure the acid mantle is reinstalling itself excreting acids by the skin again.

original in German:
<Seifen sind deutlich basisch und „trocknen“ die Haut aus, sie entfernen die Fettschicht und zerstören die Säureschicht.> [web01]

<Die eingelagerten Säuren wollen über die Haut entweichen, was grundsätzlich am leichtesten in einem basischen Umfeld möglich ist. [...] Da Säuren und Basen immer eine Reaktion eingehen, regt die basische Hautpflege den Körper an, die eingelagerten Säuren und Schlacken aus dem überwiegend sauren Milieu der Zellen zu lösen und in die basische Umgebung abzugeben. Auf diese Weise hilft eine basische Hautpflege dem Körper effektiv bei seiner Entsäuerung. [...] Die Talgdrüsen werden angeregt, die natürliche Rückfettung der Haut zu aktivieren.> [web02]


Translation:
<Soaps are considerably basic "drying" out the skin, they delete the fatty layer and they are destroying the acid layer.> [web01]

<The deposed acids want to slip away by the skin what is basically possible in a basic alkaline environment [...] As acids and basics always have a reaction basic body cure is stimulating the body to detach the deposed acids and slags from the sour dominated environment of the cells giving the slags to the basic environment. By this a basic body cure is helping to deacidify the body effectively. [...] Oil glands are also stimulated to activate forming of a new fatty layer.> [web02]


Sour soaps and sour detergents are damaging the skin
The claim that one should protect the "acid mantle" is WRONG. When sour detergents are applied the body is only more and more acid because acids cannot slip away passing the skin any more [web02].

Original in German:
<Wer über einen langen Zeitraum eine saure und zu allem Überfluss auch noch chemisch hergestellte Körperpflege verwendet, erzeugt im Körper eine Säureflut, die enorme körperchemische Wirkungen hervorruft. Die eingelagerten Säuren wollen über die Haut entweichen, was grundsätzlich am leichtesten in einem basischen Umfeld möglich ist. Wirken wir diesem Bestreben durch das Einreiben mit einer sauren Körperlotion entgegen, werden die Säuren wieder in die Körpersäfte zurückgedrängt. Die Folge ist, dass die Säuren zu einem späteren Zeitpunkt wieder austreten wollen. Der Anwender saurer Hautpflegeprodukte hat schnell das Gefühl, sich wieder reinigen zu müssen. Daher ist es keine Seltenheit, dass viele Menschen sogar öfter als einmal täglich duschen.> [web02]


Translation:
<Persons applying a sour and chemically produced body care is provoking an acid tsunami provoking an enormous bodily chemical effect. Acid deposits want to slip away by the skin what is principally possible in a basic environment. When we block this movement applying sour body lotions the acids are pressed back into the body juices. The consequence is that the acids want to slip away later. The persons applying sour skin care products have fast the feeling that they have to wash themselves again. Therefore it's not rare that many persons are taking a shower even several times per day.> [web02]

Sour soaps and detergents are attacking the skin and are provoking dermatophytes and itching etc.

original in German:
<Immer häufiger reagiert die Haut auch allergisch auf eine chemisch saure Körperpflege. Die Reaktionen reichen von unangenehmem Hautjucken über Brennen bis hin zu teilweise offenen Hautstellen. Ist die Haut angegriffen, bietet sie eine ideale Brutstätte für Hautpilze aller Art. Ein saures Hautmilieu ermöglicht die Ausbreitung von Genital-, Fuss-, Nagel- und Hautpilzen. Betrachtet man das masslose Pflegebedürfnis des Menschen der Neuzeit, wundert es nicht, dass die Anzahl der Pilzinfektionen stetig steigt.> [web02]


Translation:
<Always more skin is also reacting in an allergic way against chemical sour body care. The reaction can be from itches to burning feeling up to open skin. When skin is attacked these zones are the perfect breeding places for dermatophytes of all kind. A sour skin environment is facilitating the spreading of dermatophytes in the genital zone, on the feet (athlet's foot), under the nails (nail fungus) and on the skin. Considering the cure desire of humans of our times it's no wonder that the number of fungal infections is always rising.> [web02]

Fungal infections can only live in a sour environment - therefore a soap should be basic alkaline:

<Fungal skin infection [...] can only live when a sour body environment is found.> [web02]
(original in German: <Hautpilz [...] ist nur dann überlebensfähig, wenn er ein saures Körpermilieu vorfindet.> [web02])

pH value in the vagina and sperm
<Vagina of a woman is sour for killing germs. Sperm of the man is basic. Spermium is coming and is provoking a neutral environment then for the best movement activity.> [web01]
(original in German: <Die Scheide der Frau ist sauer, um Krankheitserreger abzutöten. Das Sperma des Mannes ist basisch. Das Spermium kommt dann in ein neutrales Milieu zur optimalen Bewegung.> [web01])

pH value of water

Here are some pH values of different water types:
-- bath water with a basic bath salt: pH8.5 [web02]
-- Kangen water: basic [web04]
-- bath water without supplements: pH7 neutral [web02]
-- tap water: pH6.5-9.5 [web01]
-- mineral water with carbonic acid: pH6.0 [web01]
-- bath water after 1 hour of bath: sour [web01]
-- water (depending on hardness) pH6.0-8.5 [web01]
-- pure water [H2O] 7.0 [web01].

<According to drinking water regulations drinking water from the tap has to be with a pH value between 6.5 and 9.5. pH value of tap water can be arranged with chemicals to the desired pH level.> [web01]
(original in German: <Gemäß der Trinkwasserverordnung darf das Trinkwasser aus der Leitung einen pH-Wert zwischen 6,5 und 9,5 aufweisen. Das Wasser kann mit Chemikalien auf den gewünschten Wert eingestellt werden.> [web01])

Bath water is becoming sour in the course of the time:

<When the bathing person is leaving the bath water after about one hour pH value has sunk considerably. This is the proof that the bath water is taking acids which were excreted from the bathing body reaching the bathing water by slipping away passing the skin.> [web01]
(original in German: <Verlässt der Badende nach ca. einer Stunde Badedauer das Wasser, ist der pH-Wert messbar gesunken. Damit wird der Beweis erbracht, dass das Badewasser die Säuren aufnimmt, die vom Körper ausgeschieden wurden und über die Haut in das Wasser gelangt sind.> [web01])
