Carbonates | CIE IGCSE Chemistry Revision Notes

Manufacture of lime. Limestone consists mainly of calcium carbonate, CaCO 3; Lime which is calcium oxide, is manufactured from calcium carbonate by thermal decomposition:; CaCO 3 → CaO + CO 2. Slaked lime, calcium hydroxide, is made by adding a small amount of water slowly to calcium oxide:; CaO + H 2 O → Ca(OH) 2. Limewater is a solution of calcium hydroxide in water, hence it is alkaline
