Answer:

The pH of the solution is 6.35.

Explanation:

Concentration of hydroxide ions = [tex][OH^-]=2.20\times 10^{-8} M[/tex]

pH + pOH = 14

pH = 14 - pOH

[tex]pOH=-\log[OH^-][/tex]

[tex]pOH=-\log[2.20\times 10^{-8} M]=7.65[/tex]

[tex]pH=14-pOH=14-7.65=6.35[/tex]

The pH of the solution is 6.35.
