Zinc Phosphate Reactions:

3Zn(C2H3O2)2 + 2Na3PO4 = 6NaC2H3O2 + Zn3(PO4)2↓

3Zn + 2H3PO4 = Zn3(PO4)2↓ + 3H2

Zn3(PO4)2 + 6HCl = 3ZnCl2 + 2H3PO4

3Zn(OH)2 + 2H3PO4 = Zn3(PO4)2↓ + 6H2O

3Mg + Zn3(PO4)2 = Mg3(PO4)2↓ + 3Zn

3Zn(NO3)2 + 2Na3PO4 = 6NaNO3 + Zn3 (PO4)2↓

2Na3PO4 + 3ZnSO4 = 3Na2SO4 + Zn3 (PO4)2↓

3Zn(NO3)2 + 2K3PO4 = Zn3 (PO4)2↓ + 6KNO3

6KCl + Zn3(PO4)2 = 3ZnCl2 + 2K3PO4

2(NH4)3PO4 + 3Zn(NO3)2 = 6NH4NO3 + Zn3 (PO4)2↓
