Answer 2

Answer:

Formula of AMMONIUM PHOSPHATE IS (NH4)3PO4.

Formula using criss cross method-

valency of NH4 = +1

valency of PO4 = -3

NH4 × PO4

+1 -3

valency of ammonium shifted to phosphate and valency of phosphate shifted to ammonium.

[plus and minus sign are not considered]

So, It becomes (NH4)3PO4
