Write equations to show the step wise ionization of the polyprotic acids `H_(2)SO_(4)` and `H_(3)PO_(4)`.

Explanation

`H_(2)SO_(4)(aq)hArrHSO_(4)^(-)(aq)+H^(+)(aq)`
`HSO_(4)^(-)(aq)hArrSO_(4)^(2-)(aq)+H^(+)(aq)`
`H_(3)PO_(4)(aq)hArrH_(2)PO_(4)^(-)(aq)+H^(+)(aq)`
`H_(2)PO_(4)^(-)(aq)hArrHPO_(4)^(2-)(aq)+H^(+)(aq)`
`HPO_(4)^(-)(aq)hArrPO_(4)^(3-)(aq)+H^(+)(aq)`
