Answer
(a) Na2CO3 solution — Red litmus changes to blue as Na2CO3 gives alkaline solution.
(b) NaCl solution — No change in the colour of the litmus paper as NaCl solution is neutral.
(c) NH4NO3 solution — Acidic so blue litmus changes to red.
(d) MgCl2 solution — Blue litmus changes to red showing acidic nature.
