formation of water soluble calcium bicarbonate
When CO2 is passed through lime water, it turns milky due to the formation of calcium carbonate which is sinsoluble in water.
limewaterCa(OH)2+CO2milkinessCaCO3+H2O
However, when excess of CO2 is passed through this solution, the milkiness disappears. This is due to the formation of calcium bicarbonate which is colorless and soluble in water.
