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

there is none because earth is stationary and flat.
