c. What could liquid C be?

d. How will you separate the mixture containing A, B
and C?​

Answer 1

Explanation:

Constituent B is a blue coloured salt, which is insoluble in carbon disulphide but dissolves in water. So, it could be copper sulphate. ... Liquid E could be water as it dissolves copper sulphate. Liquid C could be vegetable oil as it turns into a solid fat on hydrogenation.
