Title: How to find the product of this chemical equation?
Post by: ilindsey05 on Feb 15, 2013
How do you find the product equation of:
(NH4)(H2)(PO4)+ H2O-> ?
I put the parenthesis in so you won't have trouble figuring out if the numbers are next to the element or are a part of the element. I'd like to know the step by step process so I can refresh my mind on how to do these kind of equations. Thanks.

Product???   Ammonium dihydrogen phosphate will dissociate in water to make ammonium ions and dihydrogen phosphate ions.  Of course there will be all manner of H+ exchanges going on, and the concentration of the various species will depend on the pH of the solution.  Ammonium dihydrogen phosphate occurs in an acidic medium.

NH4H2PO4(s) ---H2O---> NH4+ + H2PO4-

Some of the various reactions that will be occurring:
NH4+ + H2O <==> NH3 + H3O+
H2PO4- + H2O <==> HPO4^2- + H3O+
H2PO4- + H3O+ <==> H3PO4 + H2O
