Electrolysis of aqueous (NH4)2HPO4
Well i just thought of electrolysing that. Dont know what it will produce, but i guess its gonna make NH3 and H3PO4.
Can someone tell ?

heating it (melting it) produces gaseous H3PO4 and NH3

H3PO4 does not evaporate. Melting causes loss of NH3 to form orthophosphoric acid. I remember reading a paper claiming that some of the ammonia
remains trapped when monoammonium phosphate is melted. Likely, much more is trapped when diammonium phosphate is used instead

You don't know the water electrolysis equation and yet you want to perform it?
2 H2O -> 2 H2 + O2
Start with the wikipedia entry and then follow its references: Electrolysis of water
…there is a human touch of the cultist “believer” in every theorist that he must struggle against as being
unworthy of the scientist. Some of the greatest men of science have publicly repudiated a theory which earlier they hotly defended. In this lies their
scientific temper, not in the scientific defense of the theory. - Weston La Barre (Ghost Dance, 1972)

LOL
I was talking about electrolysis of Diammonium Phosphate solution.

I imagine at the cathode
2 NH4 + 2 e- --> 2 NH3 + H2
The hydrogen gas would easily escape while the ammonia would stay dissolved in the water and turn back into the ammonium ion.
I'm not sure what would have to the HPO4- ion at the anode.
