Chain of reactions:

P → Mg3P2 → P2O5 → H3PO4 → K3PO4 → Ca3 (PO4) 2

Transition reaction equations:

# 1 Alloy phosphorus with magnesium:

2P + 3Mg = Mg3P2

# 2.Oxidation of phosphide with oxygen:

Mg3P2 + 4O2 = 3MgO + P2O5

# 3. Dissolving acidic oxide in water:

P2O5 + 3H2O = 2H3PO4

# 4.Acid neutralization with alkali:

H3PO4 + 3KOH = K3PO4 + 3H2O

# 5.Reaction of exchange with precipitation:

2K3PO4 + 3Ca (NO3) 2 = Ca3 (PO4) 2 ↓ + 6KNO3
