Question

What is the dispersed medium in the case of aerosol?

Answer 1

Aerosols:

• Depending upon whether the dispersing medium and dispersed phase are gas, liquid, or solid, eight types of colloidal systems are possible.
• When the dispersed phase is solid, and the dispersing medium is gas, then the colloids formed are referred to as aerosols.
• Example: Dust, smoke

So, the dispersed phase or medium in the case of aerosol is solid.
