If the pH of a solution is 5, what is the pOH?

The answer is 9

Explanation:

To answer this question, we are using the formula

pH + pOH = 14

It's a constant formula

We've been given the pH to be 5

So therefore, inserting it into the above above

5 + pOH = 14

pOH = 14-5

= 9

pOH = 9

That's the final answer
