Question

Shaurya is provided with three kinds of liquids. One is Sodium Hydroxide and other is hydrochloric acid and third is sugar solution. How will he identify them when he has only blue Litmus?​

Answer 1

Answer:

Following steps are taken to test the given liquids:

→Place a drop of each liquid on turmeric indicator. The solution which changes the colour of the indicator to red is basic in nature, i.e., it is sodium hydroxide.

→Now put a drop of sodium hydroxide on the other two liquids separately to obtain two mixtures.

→One by one place the drop of each mixture on turmeric indicator. The mixture that changes the colour of indicator red contains neutral sugar solution. While the mixture which does not show any colour change in indicator contains hydrochloric acid which was neutralised on addition of sodium hydroxide.
