To find the pH of a solution, we have to take the [tex]-log[/tex] of the [H+] of the solution. Essentially you can think that the 'p' means [tex]-log[/tex].

So to find the pH of this KOH solution, we are going to take the [tex]-log([H+])[/tex] to find the pH.

[tex]pH=-log([H+)][/tex]

[tex]pH=-log(1.87* 10^{-13}) [/tex]

[tex]pH=2.92* 10^{-4} [/tex]

Answer:

pH = 12.73

Explanation:

pH of a solution is defined as the log to base 10 of the hydrogen ion (H+) concentration of the solution.

In the question above,

H+ = 1.87×10⁻¹³M

pH = -log[H+]

pH = -log(1.87×10⁻¹³)

pH = -(-12.73)

pH = 12.73

The pH of a 1.87×10⁻¹³ KOH solution is 12.73
