When quicklime dissolves in water?
heat is absorbed
heat is evolved
oxygen is liberated
hydrogen is given off
Correct answer is B
- When quicklime is added to water, it forms slaked lime along with the evolution of heat. There will be a rise in the temperature of the bucket. Calcium oxide reacts with water to form calcium hydroxide, also called slaked lime.
- That is adding water to quicklime produces an exothermic reaction (gives out heat) and hydrated lime.
