Answer: The hydroxide ion concentration in the solution is [tex]1.778\times 10^{-11}M[/tex]
Explanation:
pOH is defined as the negative logarithm of hydroxide ion concentration present in the solution.
The equation used to calculate pOH of the solution is:
[tex]pOH=-\log[OH^-][/tex]
We are given:
pOH = 10.75
Putting values in above equation, we get:
[tex]10.75=-\log[OH^-][/tex]
[tex][OH^-]=10^{-10.75}=1.778\times 10^{-11}M[/tex]
Hence, the hydroxide ion concentration in the solution is [tex]1.778\times 10^{-11}M[/tex]
