Question

what happens when water is added to the slaked limestone. write balanced chemical equation of the reaction​

Answer 1

Answer:

The formation of slaked lime (calcium hydroxide, Ca(OH)2) when water is added to lime (CaO) is exothermic. CaO(s) + H2O (l) → Ca(OH)2(s) This reaction occurs when water is added to dry portland cement to make concrete, and heat evolution of energy as heat is evident because the mixture becomes warm.

please mark me as the brainliest

Answer 2

Answer:

Adding water to the lime produces slaked lime (calcium hydroxide) in an exothermic reaction. CaO(s) + H2O(l) → Ca(OH)2(s) Some of the calcium hydroxide dissolves in the water producing an alkaline solution called limewater.
