Explanation
Slaked lime, or calcium hydroxide, produced when quicklime reacts with water, has traditionally been used for whitewashing walls and buildings, giving them a bright white protective and decorative coating. It is also used in water treatment to adjust acidity levels and in some agricultural applications to reduce soil acidity. Over time, when exposed to air, slaked lime gradually reacts with carbon dioxide and converts back into calcium carbonate. Explore more Everyday Science MCQs on mcqstutor to keep practicing.
