We´re being asked to show how H3PO4 ionizes in water.

H3POis a triprotic acid, it can donate three hydronium ions (H+and it will have three equilibrium reactions.

Each equilibrium reaction has its own equilibrium constant (Ka), which related products over reactants:

$\overline{){{\mathbf{K}}}_{{\mathbf{a}}}{\mathbf{=}}\frac{\left[\mathbf{p}\mathbf{r}\mathbf{o}\mathbf{d}\mathbf{u}\mathbf{c}\mathbf{t}\mathbf{s}\right]}{\left[\mathbf{r}\mathbf{e}\mathbf{a}\mathbf{c}\mathbf{t}\mathbf{a}\mathbf{n}\mathbf{t}\mathbf{s}\right]}}$
