1) CaO + H2SO4 = CaSO4 + H2O (when calcium oxide interacts with sulfuric acid, calcium sulfate and water are formed);
2) CaSO4 + 2NaOH = Na2SO4 + Ca (OH) 2 (when calcium sulfate interacts with sodium hydroxide, sodium sulfate calcium hydroxide is formed);
3) 3Ca (OH) 2 + 2H3PO4 = Ca3 (PO4) 2 + 6H2O (when calcium hydroxide interacts with phosphoric acid, calcium orthophosphate and water are formed).
