Detailed explanation-1: -When carbon dioxide gas is passed through lime water, it turns milky due to the formation of calcium carbonate. Lime water has Calcium Hydroxide in it. When you add Carbon Dioxide to it, a white colour Calcium Carbonate is formed, which gives a milky colour to the Lime Water.

Detailed explanation-2: -Reason (R): Carbon dioxide reacts with limewater to form calcium hydrogen carbonate which forms a white precipitate.

Detailed explanation-3: -Reaction with limewater Carbon dioxide reacts with limewater (a solution of calcium hydroxide, Ca(OH) 2), to form a white precipitate (appears milky) of calcium carbonate, CaCO 3.

Detailed explanation-4: -When carbon dioxide reacts with the lime water Ca(OH)2, it forms calcium carbonate CaCO3 which turns lime water milky.

Detailed explanation-5: -Carbon dioxide passed into limewater gives a milky solution. This is due to the insoluble suspension of calcium carbonate formed: Ca(OH)2(aq)+CO2(g)→CaCO3(s)+H2O(l)
