2P + 3Mg = Mg3P2
P – oxidizing agent, process – reduction, Mg – reducing agent, process – oxidation.
2|P0 + 3е = P3-
3|Mg0 – 2е = Mg2+
Mg3P2 + 6H2O = 2PH3 + 3Mg(OH)2
2PH3 + 4O2 = P2O5 + 3H2O
P – reducing agent, process – oxidation, O – oxidizing agent, process – reduction.
1|P3- – 8е = P5+
4|O0 + 2e = O2-
P2O5 + 3H2O = 2H3PO4
2H3PO4 + 3CaO = Ca3(PO4)2 + 3H2O
