Answer 2

Answer: Hi , good morning

Here's your answer

When quick lime reacts with water, water and quick lime go under combination reaction and give calcium hydroxide.[ slaked lime ]

CaO + H2O ⇒ Ca[OH]2 + Heat [ exothermic ]

 This calcium hydroxide (slaked lime) is used in white washing of walls.

It reacts slowly with carbon dioxide in air to form a thin layer of calcium carbonate on the walls.  Calcium carbonate is formed after two to three days of whitewashing and gives a shiny finish to the walls.

Ca[OH]2 + CO2 ⇒ CaCO3
