Answer:
Hydrolisys of CaOHCl
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)
- CaOHCl + H2O → Ca(OH)2 + HCl
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.
