What is the pOH of a 2.1x10^-6 m oh - solution?

pOH=?

The answer to your question is: pOH = 5.7

Explanation:

pOH is a measure of the concentration of OH ions.

Data

pOH = ?

Molarity = 2.1 x 10 ⁻⁶ M

Formula

pOH = - log [OH]

Substitution

pOH = - log[2.1 x 10⁻⁶]

pOH = 5.7

and pH = 14 - pOH

pH = 14 - 5.7

pH = 8.3
