what happens when CO2 is passed through freshly prepared slaked lime ? write a balanced chemical equation ?
Slaked lime is chemically calcium hydroxide or Ca(OH)2. A saturated solution of calcium hydroxide in water is known as lime water. When carbon dioxide is passed through a freshly prepared solution of lime water, then it turns milky due to the formation of calcium carbonate, which is insoluble in water. Following is the chemical equation for the reaction
Ca(OH)2 + CO2 → CaCO3 + H2O
