Question

If the oh is 6.46(10^-9)M what is the pOH

Answer 1

Answer: Thus pOH has value of 8.19

Explanation:

pH or pOH is the measure of acidity or alkalinity of a solution.

pOH is calculated by taking negative logarithm of hydroxide  ion concentration.

$pOH=-\log [OH^-]$

Putting in the values:

$pOH=-\log[6.46\times 10^{-9}]$

$pOH=8.19$

Thus pOH has value of 8.19
