0.01 M solution of You can't use 'macro parameter character #' in math mode has pH 4. If You can't use 'macro parameter character #' in math mode for acid is 3.12×You can't use 'macro parameter character #' in math mode . concentration is?
"0.01 M solution of $H_2A$ has pH equal to 4. If $K_{a1}$ for the acid is $4.45 \times 10^{-7}$, the concentration of $HA^-$ ion in solution would be Question no 10"
