Explanation:
Detailed explanation-1: -Final answer: Dilution of an acid and Reaction of water with Quicklime are exothermic processes.
Detailed explanation-2: -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.
Detailed explanation-3: -CaO ( s ) Quick lime + H 2 O ( l ) Water → Ca ( OH ) 2 ( s ) + ∆ Slaked lime.
Detailed explanation-4: -The slaking of lime is an endothermic change.
