Explanation:

Answer:- 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 insoluble in water.  

Ca(OH)2+CO2CaCO3(milkiness)+H2O(water  

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.

CaCO3(milkiness)  +H2O+CO2(excess)

⟶  

Ca(HCO3)2(water soluble)
