Answer 1

Answer:

Take 3 small pieces of red litmus paper. Put one drop each of the given solutions on these litmus papers.

The liquid which turns Red litmus, into Blue, is a Basic Solution.

Divide the blue litmus paper, so formed into two parts. Put one drop each of the other two liquids seperately on these two pieces of litmus paper.

The solution which turns Blue litmus paper, into Red, is an Acidic Solution.

The solution which does not have any affect on the colour of litmus paper is Distilled Water.
