What is the pH of hydrochloric acid in stomach?

Answer 1

This depends on the concentration; for example, the pH of a 10% solution is -0.5, but that of a 30% solution is -1.0.
There are two points to make about this question. First, the pH of any acid or any substance depends upon its concentration in water, usually given by chemists in the form of moles per liter. Secondly, there is no hydrocolic acid, you are probably thinking of hydrochloric acid, which is quite strong as acids go, and in a high concentration could have a pH of 1.

Answer 2

Hydrochloric acid cannot be assigned a pH value. pH is a measure of the hydrogen ion concentration in an aqueous solution, not the strength of an acid.

Because hydrochloric acid is a weak monoprotic acid the pH of a solution of it is fairly easily calculated.

pH=-log[HCl], where [HCL] is the concentration of the hydrochloric acid in moles per liter.

Answer 3

There is no set pH for hydrochloric acid or any single acid.

pH is not a measure of the strength of an acid or but a measure of the concentration of hydrogen ions (H+) in a solution of water and so is dependent on both the strength of an acid or base and on its concentration (how much is dissolved in a given volume of water).

Since hydrochloric acid is a strong acid a solution of it will most often ave a pH ranging from 2 to 0, though pH values of nearly 7 are possible with very low concentrations.

Answer 4

pH depends on the concentration of the acid as much as the strength. As HCl is a strong monoprotic acid the pH will be equal to the negative logarithm of its molar concentration.

(a 1M solution will have a pH of 0, a .1 molar solution will have a pH of 1, etc.)

Answer 5

Gastric acid is a digestive fluid, formed in the stomach. It has a pH of 1.5 to 3.5 and is composed of hydrochloric acid (HCl) (around 0.5%, or 5000 parts per million), and large quantities of potassium chloride (KCl) and sodium chloride (NaCl).

The pH of the medium is low (high acid concentration). However the layer on the inner part of the stomach, prevents the acid from corroding the internal organs.

Answer 6

it is around about 1 or 2 as Hydrochloric acid is very acidic!

Answer 7

The pH of hydrochloric acid is 2.

Answer 8

pH 1 to 2.
