State the change noticed when blue litmus and red litmus are introduced in the following solutions:

(a) Na2CO3 solution

(b) NaCl solution

(c) NH4NO3

(d) MgCl2 Solution

 

Best Answer

(a) Na2CO3 solution: This solution is alkaline in nature; hence, red litmus changes to blue.

(b) NaCl solution: There is no change in the colour of the litmus paper because this solution is neutral.

(c) NH4NO3: This solution is alkaline in nature; hence, red litmus changes to blue.

(d) MgCl2: It is slightly acidic and neutral; hence, there is no change in the litmus paper.
