The pH of the solution is 1.

In aqueous solutions, the concentration of hydronium ions ([H₃O+]) and hydroxide ions ([OH-]) are related by the ion product constant of water (Kw) at a specific temperature:

Kw = [H₃O+][OH-] = 1.0 x 10⁻¹⁴ at 25°C

We are given that the [OH-] value is 10⁻¹³. We can use the Kw expression to calculate the [H₃O+] concentration:

[H₃O+] = Kw / [OH-]

[H₃O+] = (1.0 x 10⁻¹⁴) / (10⁻¹³)

[H₃O+] = 1.0 x 10⁻¹

Now that we know the [H₃O+] concentration, we can calculate the pH of the solution using the following equation:

pH = -log([H₃O+])

pH = -log(1.0 x 10⁻¹)

pH = 1

Therefore, the pH of the solution is 1.
