Give reason why carbon dioxide turns lime water milky |
|
Answer» When\xa0CO2\u200b\xa0passes through lime water, it turns into milky lime water due to formation of insoluble calcium carbonate.\xa0Ca(OH)2\u200b+CO2\u200b⇌CaCO3\u200b(+)+H2\u200bOIOf\xa0CO2\u200b\xa0is passed for longer period, turbidity disappears due to form of soluble calcium bicarbonate.CaCO3\u200b+H2\u200bO+CO2\u200b⇌Ca(HCO3\u200b)2\u200b\xa0. The reaction between limewater, which is a solution of calcium hydroxide, Ca(OH)2 , and carbon dioxide will result in the formation of an insoluble solid called calcium carbonate, CaCO3 . The solution will turn milky due to the fact that calcium carbonate is a white precipitate. |
