A
Lyophilic colloids are stable colloids
B
Lyophobic colloids are self-stabilised.
C
Lyophobic colloids need stabilising agents.
D
Lyophilic colloids are reversible.
Solution:
Homogeneous and heterogeneous are two categories into which mixtures are divided. True solutions are homogeneous and are made up of tiny particles whose size is less than 1nm. Homogeneous mixtures are known as solutions. Suspension and colloids are examples of heterogeneous mixtures. True solutions cannot be separated by physical processes. Lyophilic colloids are water-attracting, while lyophobic colloids are water-repellant colloids. Lyophilic colloids are reversible, while lyophobic colloids are irreversible. Lyophobic colloids are stabilised by adding lyophilic colloids.
