Question

What is the pOH of a solution with an OH- ion concentration of 8.4E-7?

Answer 1

Answer:

6.08

Explanation:

The pOH of a solution can be found by using the formula

$pOH = - log [ {OH}^{-} ]$

From the question we have

$pOH = - log(8.4 \times {10}^{ - 7} ) \\ = 6.075720...$

We have the final answer as

6.08

Hope this helps you
