Problem

Calculate

[\text{H}^+]

, pH,

[\text{CH}_3\text{COO}^-]

and

[\text{C}_7\text{H}_5\text{O}_2^-]

in a solution containing 0.02 M

\text{CH}_3\text{COOH}

and 0.01 M

\text{C}_6\text{H}_5\text{COOH}

K_{\text{CH}_3\text{COOH}} = 1.8 \times 10^{-5}

and

K_{\text{C}_6\text{H}_5\text{COOH}} = 6.4 \times 10^{-5}
