Question

A man wanted her house to be whitewashed. He bought 8 kg of lime and dissolved it in
15 litres of water. On adding water lime to water he noticed that water started boiling even when
it is not being heated. Give reasons for his observation. Write the corresponding chemical equation and the product formed.

Answer 1

Lime reacts readily with water to produce slaked lime, which is the chemical compound calcium hydroxide. As it's an exothermic reaction, a considerable amount of heat energy is released during this reaction.

Reaction: CaO + H2O ----> Ca(OH)2
