Answer 2

Answer:

When it reacts with bases (like baking soda), it changes color to deep red. This red form of the indicator can change back to yellow when acids are added. Thus the color of the chemical “indicates” the presence of an acid or base.

A blue litmus paper turns red if solution is acidic. So, Vinegar solution turns paper red. A red litmus paper turns blue if solution is alkaline. So, solution of baking soda turns paper blue.
