Given a solution with a poh of 13.6, what is the [oh-] of the solution?

13.6 m

2.51 x 10-14 m

0.4 m

3.98 x 10-1 m

2.51 x 10-14 M

Explanation:

The definition of pOH is:

pOH = -log[OH-]

then, clearing of the equation [OH-] we have:

-pOH = log[OH-]

By properties of logarithms:

Replacing the values:

And if you use a calculator, you will see that
