When heated to a high temperature, limestone decomposes into lime with a release of carbon dioxide gas. CaCO3(s) + heat CaO (s) + CO2(g) limestone lime carbon dioxide Adding water to the lime 'slakes' it. Considerable heat is released in this reaction. CaO(s) + H2O( l ) Ca(OH)2(s) + heat The lime plaster is a mix of slaked lime and sand.
