The pH of a solution is calculated using the formula pH = -log[H+], where [H+] is the concentration of hydrogen ions in the solution.

In this case, the HCl is a strong acid and will completely dissociate in water to form H+ and Cl- ions. Therefore, the concentration of H+ ions is equal to the concentration of the HCl solution, which is 10^-4 M.

Substituting this into the formula gives:

pH = -log(10^-4)
= 4

So, the pH of a 10^-4 M solution of HCl is 4.
