Calcium carbide → Calcium hydroxide → Calcium carbonate → Calcium oxide → Calcium chloride
CaC2 → Ca (OH) 2 → CaCO3 → CaO → CaCl2
1) CaC2 + 2H2O → Ca (OH) 2 ↓ + C2H2 (exchange reaction);
2) Ca (OH) 2 ↓ + H2CO3 → 2H2O + CaCO3 ↓ (exchange reaction);
3) CaCO3 ↓ → CO2 ↑ + CaO (decomposition reaction);
4) CaO + 2HCl → CaCl2 + H2O (exchange reaction).
