Answer: The hydroxide ion concentration in aqueous solution is [tex]1.412\times 10^{-10}M[/tex]
Explanation:
To calculate the hydroxide ion concentration, we use the equation:
[tex]pOH=-\log[OH^-][/tex]
We are given:
pOH = 9.85
Putting values in above equation, we get:
[tex]9.85=-\log[OH^-][/tex]
[tex][OH^-]=10^{-9.85}=1.412\times 10^{-10}M[/tex]
Hence, the hydroxide ion concentration in aqueous solution is [tex]1.412\times 10^{-10}M[/tex]
