1.	When CO2 gas is passed in lime water it turns milky but in case of excess CO2, milkiness disappeard. Support the statement by giving suitable reaction equations.
Answer» When CO₂gas is passed in lime water, it turns milky due to the formation of calcium carbonate. Ca(OH)₂ + CO₂ → CaCO₃ + H₂O On passing excess of CO₂, milkiness disappears because the precipitate dissolves to form calcium hydrogen carbonate. CaCO₃ + CO₂ + H₂O → Ca(HCO₃)₂

Answer»

When CO₂gas is passed in lime water, it turns milky due to the formation of calcium carbonate.

Ca(OH)₂ + CO₂ → CaCO₃ + H₂O

On passing excess of CO₂, milkiness disappears because the precipitate dissolves to form calcium hydrogen carbonate.

CaCO₃ + CO₂ + H₂O → Ca(HCO₃)₂
