Question

what are the demerits of the reaction between carbon dioxide and lime water?​

Answer 1

Answer:

When carbon dioxide reacts with lime water (calcium hydroxide solution), a white precipitate of calcium carbonate is produced. The solution of calcium hydroxide is limewater and if carbon dioxide bubbles through the limewater, it turns cloudy white or milky.

Answer 2

Explanation:

The reaction between limewater, which is a solution of calcium hydroxide, Ca(OH)2 , and carbon dioxide will result in the formation of an insoluble solid called calcium carbonate, CaCO3 . The solution will turn milky due to the fact that calcium carbonate is a white precipitate.
