Question

Arnab is provided with three kinds of liquid. out of them one is sodium Hydroxide another is Hcl and third is sugar solution. how will we identify them. then he is only turmeric indicator

Answer 1

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.
