What is the balanced equation for NaH2PO4 + H2O?

Is it NaH2PO4 + H2O ----> PO4^3- + H3O^+ + 2Na^+ ?

Can someone tell me if I am writing this equation right? I am trying to show the ion that is reacting in the solution. The solution: Al2(SO4)3

Equation: Al^+3 + H2O <----> Al(OH)^+2 + H^+

Does anyone know how to determine the hydrated ion that affects the pH of a solution? Ex. NaCl solution, NaCH3CO2 solution, ect.

I think it would be the Cl- ion in a solution of NaCl, but not so sure...

Does anyone know?.... : -)

I got this:

AlCl3 pH=7 AlCL3 + H2O ----> AlOH^- + H^+

K3PO4 pH>7 K3PO4 + H2O -----> HPO4 + OH^-

Na2SO4 pH>7 Na2SO4 + H2O ----> HSO4 + OH^-

Ca(CH3CO2)2 pH>7 Ca(CH3CO2)2 + H2O -----> CH3CO2 + OH^-

Predict whether an aqueous solution of each salt produces a solution with a pH >7, <7, or = 7. If the pH >7 or <7, write an equation that justifies your prediction. SALT: AlCl3, K3PO4, Na2SO4, Ca(CH3CO2)2:doh:
