Question

Arnav is provided with three kinds of liquid of them one is sodium hydroxide another
is hydrochloric acid and and third is a sugar solution . How will he identify them when
he have only turmeric indicator.

Answer 1

First he should take turmeric indicator and put a drop of sodium hydroxide , if it changes to red then it means that it is a base then put hydrochloric acid into the red solution , if it changes into yellow then it is acid and now put sugar solution in it, if it colour doesn't change then it means that it is a neutral solution.

Answer 2

Answer:

Turmeric is a good indicator of acids and bases. It turns red in bases whereas it is yellow in both acids and neutral solutions. When we mix turmeric to the three liquids, sodium hydroxide turns it into red so we conclude that it is a base. Hydrochloric acid and sugar solution keep turmeric in yellow colour.
