1.	What do you observe in the reaction of CO2 with lime water
Answer» Formation of water soluble calcium bicarbonateWhen CO2\u200b is passed through lime water, it turns milky due to the formation of calcium carbonate which is sinsoluble in water.limewaterCa(OH)2\u200b\u200b+CO2\u200b⟶milkinessCaCO3\u200b\u200b+H2\u200bOHowever, when excess of CO2\u200b is passed through this solution, the milkiness disappears. This is due to the formation of calcium bicarbonate which is colorless and soluble in water.milkinessCaCO3 \u200b\u200b+H2\u200bO+excessCO2\u200b\u200b⟶water\xa0solubleCa(HCO3\u200b)2
