Answer:
Hydroxyl ion concentration is [tex]5.08\times10^{-11}M[/tex].
Explanation:
From the given,
pH of the solution = 11.30
pH+pOH = 14
11.30 + pOH = 14
pOH = 14-11.30 = 2.7
The pOH of the solution is 2.7
Concentration of hydroxyl ion:
[tex]2.7= -log[OH^{-}][/tex]
[tex]log[OH^{-}]= -2.7=5.08\times10^{-11}M[/tex]
Therefore, hydroxylion concentration is [tex]5.08\times10^{-11}M[/tex].
