Answer:
Aim: Formation of slaked lime by the reaction of calcium oxide with water
➡Apparatus: Calcium oxide, beaker, and water
➡Procedure: Take a small amount of calcium oxide or quick lime in a beaker. Slowly add water to this. Touch the beaker
➡Observation: The beaker becomes hot (exothermic reaction). It reacts vigorously with water.
➡Conclusion: Slaked lime is formed by the reaction of the combination of calcium oxide with water
CaO(s) + H2O(l) → Ca(OH)2(aq) + heat
(quick lime) (Slaked lime) (exothermic reaction)
This is a combination reaction, and also an exothermic reaction.
