1.	When carbon dioxide is passed into limewater,the limewater turn milky.why?
Answer» When CO2\u200b passes through lime water, it turns into milky lime water due to formation of insoluble calcium carbonate.Ca(OH)2\u200b + CO2\u200b⇌CaCO3\u200b(+) + H2\u200bOIOf CO2\u200b is passed for longer period, turbidity disappears due to form of soluble calcium bicarbonate.CaCO3\u200b + H2\u200bO+ CO2\u200b ⇌ Ca(HCO3\u200b)2\u200b . When carbon dioxide is passed through lime water, it turns lime water due to formation of white precipitate of calcium carbonate.
