Answer 1

(c) Albumin on shaking with water will not form a true solution.

• What is a true solution?

It is a homogenous mixture of two or more substance in which the size of the solute particles are less than $10^{-8}$ cm.

• Why albumin cannot form a true solution with water?

Albumin will form a colloidal solution instead of a true solution as it is not soluble in water.
