Calculate `[H^(+)], [CH_(3)COO^(-)]` and `[C_(7)H_(8)O_(2)^(-)]` in a solution that is `0.02M` in acetic acid and `0.01M` in benzoic acid. `(K_(a_(A A))= 1.8xx10^(-5), K_(a_(BA)) = 6.4xx10^(-5))`

Text Solution

Verified by Experts

The correct Answer is:
`[H^(+)]=10^(-3)M, [CH_(3)COO^(-)]=3.6 xx 10^(-4)M, [C_(7)H_(5)O_(2)^(-)]=6.4 xx 10^(-4)M`
