Identify the salt that is produced from the acid–base neutralization reaction between (b) ammonia and phosphoric acid.

I know that phosphoric acid is a triprotic acid, from its formula H3PO4. The first equation for the reaction between ammonia and phosphoric acid is:
NH3 + H3PO4 -> NH4H2PO4. How do you know that the product is NH4H2PO4 and not H2PO4 + NH4? Shouldn't H3PO4 donate its proton to NH3, making the products be NH4 + H2PO4?

I believe they are the same product, just in a different notation. H3PO4 did donate its proton to NH3. Don't forget that each compund has a charge on it, so as long as you make sure that they cancel out when put together like the product is given in the solution manual, the product given is correct as well. Hope this helps!
