this is due to the unsoluble suspension of calcium carbonate formed . the milkyness disappears since calcium bicarbonate is water -soluble

Heya user
Here is your answer !!
When carbon dioxide is passed through lime water [ Ca(OH)2 ] , calcium carbonate is formed .
Calcium carbonate is white in colour and is insoluble in water .
So , it turns lime water milky .
When excess of CO2 is passed , calcium bicarbonate is formed which is again soluble in water . Hence , the milkiness will disappear .
Ca(OH)2 + CO2 --> CaCO3 + H2O
CaCO3 + CO2 --> Ca(HCO3)2
Hope it helps !!
