The solution containing dissolved CO2 i...

The solution containing dissolved `CO_2` is 0.035 M. If the dissociation constants for the reactions
`CO_2 + H_2O = H^(+) + HCO_3^-`
`HCO_3^(-) = H^(+) + CO_3^(2-)` are `4.16 xx 10^(-7) ` and `4.84 xx 10^(-11)` respectively, calculate `[H^+]` in the solution.
