Calculate the `[OH^(-)]` of a solution whose pH is 9.62.

Text Solution

Verified by Experts

`pH+pOH=14, pOH=14-pH=14.9.62=4.38`
`pOH=4.38=-log_(10)[OH^(-)],4.38=-log_(10)[OH^(-)]`
`log_(10)[OH^(-)]=-4.38, [OH^(-)]=` antiolog `(-4.38)=` antilog `(5-4.38-5)`
`=` antilog `(0.62-5)=`antilog `(0.62)xx10^(-5)=4.269xx10^(-5)"mol"dm^(-3)`
