Question

complete the reaction Ca(OH)2+CO2-?+?​

Answer 1

Answer:

When calcium hydroxide reacts with carbon dioxide, it produces calcium carbonate and water. In this reaction, when carbon dioxide gas reacts with slaked lime called calcium hydroxide, the solution becomes milky due to the formation of calcium carbonate and calcium carbonate is insoluble in water.

Explanation:

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.
