1. Calcium oxide – basic oxide, reacting with water, forms a base – calcium hydroxide.
CaO + H2O = Ca (OH) 2.
2. When carbon dioxide is passed through a solution of lime water (calcium hydroxide), turbidity occurs – poorly soluble calcium carbonate is formed, which precipitates.
Ca (OH) 2 + CO2 = CaCO3 + H2O.
