Question

what happens when water is added to quick lime?

Answer 1

When Water is added to quick lime, then a lot of heat is released and heavy fizzing occurs because Slaked lime is fromed ( Calcium Hydroxide).

The following reaction occurs--

CaO + H₂O → Ca(OH)₂ + heat energy.

.

Answer 2

Answer:

When Quick Lime reacts with Water we get Slaked lime[ Calcium Hydroxide] and an enormous quantity of heat exists released. Hence it is an exothermic reaction:

Explanation:

An exothermic reaction exists in a reaction in which energy exists terminated in the state of light or heat. Therefore, in an exothermic reaction, energy exists transmitted into the surroundings. In an exothermic reaction, the difference in enthalpy (Δ$H$) will be negative.

The chemical name of Quicklime exists as Calcium Oxide.

When Quick Lime reacts with Water we get Slaked lime[ Calcium Hydroxide] and an enormous quantity of heat exists released.

So it is an exothermic reaction:

Chemical Equation:

$\mathrm{CaO}_{(\mathrm{s})}+\mathrm{H}_{2} \mathrm{O} \rightarrow \mathrm{Ca}(\mathrm{OH})_{2}+$ heat

Quicklime            slaked lime
