Correct Answer: Calcium carbonate
Solution : The correct option is Calcium carbonate .
The interaction between carbon dioxide and calcium hydroxide produces a white precipitate, calcium carbonate (CaCO 3 ) when carbon dioxide is passed through lime water. This is used to detect the presence of carbon dioxide. The chemical equation for the interaction of carbon dioxide (CO 2 ) and lime water (calcium hydroxide, Ca(OH) 2 ) is as follows: Ca(OH) 2 + CO 2 → CaCO 3 + H 2 O. Calcium hydroxide combines with carbon dioxide to form calcium carbonate (a white precipitate) and water.
