Select the correct statements among the following

a) Foam is a colloidal solution of gas in liquid

b) Aerosol is a colloidal solution of liquid in gas

c) Gel is a colloidal solution of solid in liquid

d) Emulsion is a colloidal solution of liquid in liquid

View answer and explanation

Correct option: A

a, b, d correct

Option A (a, b, d correct) is correct because foam is gas in liquid, aerosol is liquid in gas, and emulsion is liquid in liquid. Gel is liquid in solid.
