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.
[tex]pOH=-\log [OH^-][/tex]
Putting in the values:
[tex]pOH=-\log[6.46\times 10^{-9}][/tex]
[tex]pOH=8.19[/tex]
Thus pOH has value of 8.19
