PVIII is reduced to PV by gaining six electrons, while Zn0 is oxidized to ZnII by losing six electrons. In this reaction, PO4 acts as an oxidizing agent, while Zn acts as a reducing agent.
Balanced Chemical Equation
3 Zn + 2 PO4^3- → Zn3(PO4)2
This equation represents the reaction of three Zn atoms with two phosphate ions to produce zinc phosphate, which is represented by the formula Zn3(PO4)2. The overall reaction can be understood as a transfer of electrons from Zn atoms to phosphate ions, resulting in the formation of Zn3(PO4)2.
