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. Adding more carbon dioxide results in the precipitate dissolving to form a colourless solution of calcium hydrogencarbonate.

Answer:
When carbon dioxide is treated with lime water, it turns milky white. This can be represented in the following equation.
CaOH 2 + CO2 → CaCO3 + H2O
