Answer : 2.14
Explanation:
pH or pOH is the measure of acidity or alkalinity of a solution.
Given : [tex]NaOH\rightarrow Na^++OH^-[/tex]
1 mole of [tex]NaOH[/tex] gives 1 mole of [tex]OH^_[/tex]
Thus 0.0072 moles of [tex]NaOH[/tex] will give= 0.0072 moles of [tex]OH^_[/tex]
[tex]pOH=-\log [OH^][/tex]
[tex]pOH=-\log (0.0072)[/tex]
[tex]pOH=2.14[/tex]
Therefore, the pOH of the basic solution is 2.14.
