When CO 2
passes through lime water, it turns into milky lime water due to formation of insoluble calcium carbonate.
Ca(OH) 2 +CO 2
Ca(OH) 2 +CO 2 ⇌CaCO 3
Ca(OH) 2 +CO 2 ⇌CaCO 3 (+)+H 2 OIOf CO 2
is passed for longer period, turbidity disappears due to form of soluble calcium bicarbonate.
CaCO 3 +H 2O+CO 2 ⇌Ca(HCO 3 ) 2 .
Answer:
Due to the formation of calcium carbonate
