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)# and #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^(+)# 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 = 1.487#
