Question

Find the pOH for the following:

A 1.34 x 10^-4 M solution of hydrochloric acid.

A) 10.13

B) 3.87

C) 4

D) 10

Answer 1

Answer:

A) 10.13 is the answer

Explanation:

Since HCl is a strong acid, its pH can be found by simply plugging it into the equation:

pH = -log[H+]

*H+ is just the concentration you were given*

Now that you have the pH, you just subtract it from 14 to find the pOH
