What is the pH for a 0.10 M HCI solution at 25

degreesCelsius?

1.0

Explanation:

Hydrochloric acid is a strong acid, that is, an acid that dissociates completely, according to the following reaction.

HCl (aq) → H⁺ (aq) + Cl⁻ (aq)

Then, the concentration of H⁺ will be equal to the initial concentration of the acid, i. e., 0.10 M.

We can calculate the pH using the following expression.

pH = - log [H⁺] = - log 0.10 = 1.0
