Question

Lime water turns miky when carbon dioxide gas is passed through it and further turns colorless when excess and carbon dioxide is bubbled through. Explain

Answer 1

If CO2 is bubbled through lime water it reacts with the calcium hydroxide to produce calcium carbonate. The chemical reaction is shown below. We are reacting lime water with excess carbon dioxide(CO2). ... Calcium carbonate is very insoluble in water so it will precipitate from solution as if forms.
