How is the Hydrogen ion concentration of stomach acid - with a pH of 2.0 - found?
Wiki User
∙ 12y ago
The definition of pH is used, which is, pH=-logH+concentration.
Since you know the pH, this turns into an algebra problem:
2.0 = -logH+concentration
Then, logH+concentration = -2
H+concentration = 10-2, or 1/100. The H+ concentration is 0.01 M.

Does a acid or a base contain a higher concentration of hydrogen ions?
Concentration or quantity? Bases have more hydrogen.
How can hydrochloric acid exist in stomach without hurting you?
The concentration of hydrochloric acid in stomach is not so great; but above the normal concentration HCl is dangerous.
What you pH value when 100 percent sulfuric acid?
100% sulfuric acid rapidly decomposes until it reaches a concentration of 98%. This concentration is usually referred to as concentrated sulfuric acid. The pH value of 98% sulfuric acid is approximately -1.5 For comparison, sulfuric acid of this concentration has about 300 times as many active hydrogen ions as stomach acid (approximate pH 1).
What has a PH level of 0?
Any (Strong) acid with a hydrogen ion concentration of 1mol/L. If an acid has a greater concentration, the PH is negative.
Ph of muriatic acid?
Muratic acid (Hydrogen Chloride) at a 10% concentration has a PH of -.5. This is the concentration that is available for most houshold uses.
The strenghth of an acid is based on the concentration of what ions?
The strength of an acid is based on the concentration of hydrogen ions. Any compound with hydrogen in front of it, such as hydrochloric acid (HCl) is acidic.
Concentration of hydrogen ions in solution is called?
Concentration of hydrogen ions in a solution is called: Acid concentration and pH = - log10(hydrogen ions concentration, in mol/l)
Why is there acid found in the stomach?
Acid is found in the stomach, because the acid helps in digestion.
Does a acid or a base contain a higher concentration of hydrogen ions?
Concentration or quantity? Bases have more hydrogen.
How can hydrochloric acid exist in stomach without hurting you?
The concentration of hydrochloric acid in stomach is not so great; but above the normal concentration HCl is dangerous.
What you pH value when 100 percent sulfuric acid?
100% sulfuric acid rapidly decomposes until it reaches a concentration of 98%. This concentration is usually referred to as concentrated sulfuric acid. The pH value of 98% sulfuric acid is approximately -1.5 For comparison, sulfuric acid of this concentration has about 300 times as many active hydrogen ions as stomach acid (approximate pH 1).
Which substances decrease the H ion concentration in an solution?
An acid increase the hydrogen ion concentration in a solution.
Will hydrogen peroxide neutralize stomach acid?
No!
The acid base balance depends on the concentration of?
Hydrogen
Where in the body is the strongest acid concentration located?
The stomach has the strongest acid concentration in the body. It is known as gastric acid and has a pH of 1 to 2 and is composed of hydrochlorlic acid.
The strength of an acid based on concentration of what ions?
Hydrogen ion (H+) [technically it is hydronium ion (H3O+)] that determines the strength of an acid. A mole of hydrochloric acid (HCl) produces 1 mole of H+ ions, then that is a strong acid. Weak acids give smaller amounts of H+ for a mole of substance.
What has a PH level of 0?
Any (Strong) acid with a hydrogen ion concentration of 1mol/L. If an acid has a greater concentration, the PH is negative.
