Question

you are given a basic substance 'a' and a neutral substance 'b' in the colourless solution formed how will you distinguish between A and B using turmeric solution​

Answer 1

Explanation:

We will put a drop each of hydrochloric acid, sodium hydroxide and sugar solution on the turmeric indicator. The liquid which changes this colour of turmeric indicator to red is basic in nature that is sodium hydroxide. Now, we will put a drop of sodium hydroxide on a drop of each of the other two liquids separately. After that we will put the drops of their mixtures on turmeric indicator. The drop which will change the colour of the turmeric indicator to red contains sugar solution. This is because the mixture of base and neutral solution is basic in nature. On the other hand, the drop which will not change the colour of turmeric indicator contains hydrochloric acid because hydrochloric acid reacts with sodium hydroxide forms a neutral solution. Sodium hydroxide + Hydrochlorice acid/sugar solution → Mixture → Hydrochloric acid ←−−−−−in colourNo change Drop on turmeric solution → Colour changes to red → Sugar solution
