The pH of this solution is 1.487.

Explanation:

Since HCl is a strong acid, it completely dissociates into its respective ions when placed in water. In this case HCl ionizes to produce H^(+) (aq)H+(aq) and Cl^(-)(aq)Cl−(aq).

As soon as we know that we're dealing with a strong acid, the pH can be obtained directly from the concentration of H^(+)H+ using the following formula:

All we have to do is take the -log of the given concentration like so:

pH = -log [3.26xx10^(-2)] pH=−log[3.26×10−2]

pH = 1.487pH=1.487
