Question

Turmeric paste is deposited on blotting paper and dried. If a drop of soap solution is placed on it, What will you observe and why?

Answer 1

The colour will change to red on the place where the drop of soap solution is placed. This happens because turmeric is an indicater and soap solution is a base. And so turmeric will change it's color to red when it is in contact with a base.
