Question

what happen s chemically when quick lime is added to water Related:  Previous Year Questions - Chemical Reactions and Equations?

Answer

CaO(s)+H2O(l)~Ca(OH)2(aq)+heat.

CaO=calcium oxide(quick lime),Ca(OH)2=Calcium hydroxide(slaked lime)

Answer

Can u say me the question number of this question in previous year paper

Answer

Chemical Reaction of Quick Lime with Water

1. Dissolution of Quick Lime (Calcium Oxide)

When quick lime (CaO) is added to water (H2O), it undergoes a chemical reaction called hydration.
The quick lime dissolves in water to form calcium hydroxide (Ca(OH)2).

2. Chemical Equation of the Reaction

3. Explanation of the Reaction

During the reaction, the quick lime reacts with water to form calcium hydroxide.
This reaction is highly exothermic, meaning it releases a large amount of heat energy.
The reaction is also highly alkaline, causing the solution to become basic.

4. Physical Changes

As the quick lime dissolves in water, the solution may become hot due to the release of heat energy.
The solution may also turn milky white due to the formation of calcium hydroxide.
