Answer 1

Answer:

Aqueous calcium hydroxide reacts with carbon dioxide to form a white precipitate, calcium carbonate, and water. ... Continuing to add CO2 to limewater after it's become cloudy will cause it to become clear again. The carbonic acid that forms reacts with the calcium carbonate to form soluble calcium hydrogen carbonate.
