Answer:
Hot
Explanation:
Lime water is the common name for dilute aqueous solution of calcium hydroxide. Calcium hydroxide is sparsely soluble at room temperature in water. It is a strong base. Pure lime water is clear and colorless, with a slight earthy smell and an astringent/bitter taste. Drinking lime water improves digestion.
Sulphuric acid , also known as oil of vitriol, is a mineral acid. It is a strong oxidizing agent and a strong acid. It is a colorless, odourless and viscous liquid that is soluble in water.
Sulphuric acid is a strong acid and lime water is a strong base,they undergo complete dissociation in solution. The product has salt Calcium sulphate and water. Since it is a reaction with strong acid and a strong base, more heat is released during the reaction.
