Question

slaking of lime is a chemical change?Explain

Answer 1

If you want to make slaked lime, spray the quicklime with a limited amount of water. It will hiss and crumble, forming calcium hydroxide. If you place theslaked lime in water for a few hours, a clear solution of lime water will form which turns milky as it absorbs carbon dioxide and can thus be used to detect it.

Hence, its a chemical reaction.
