sodium chloride is contanimated with copper(ii) oxide , explain how pure sodium chloride can be obtained from the mixture
Answers
Answer:
Aim of the Activity :-
To test whether the solution of water and quick lime is acidic or basic .
Materials RequireD :-
A beaker , quick lime , water , a dropper and litmus solution .
Procedure :-
Take a beaker and pour water in it.
Carefully take a small amount of quick lime ( CaO ) and add to it.
Stir them carefully .
Allow the solution to rest for some time .
Now with the help of a dropper add the litmus solution ( red) to it.
Observations :-
Quick lime reacts vigoursly with water to form Calcium Hydroxide .
The reaction involves release of heat energy .
After the addition of litmus solution , the red color of litmus changes to blue .
The Reaction of water and quick lime is ,
\boxed{\red{\sf CaO + H_2O \to Ca(OH)_2 }}
CaO+H
2
O→Ca(OH)

Inference :-
The Calcium Hydroxide is basic in nature as it converts red litmus Solution to blue .
