Continous phase contains dispersed phase...

Continous phase contains dispersed phase throughout Example is

A

Water in milk

B

Fat in milk

C

Water droplets in mist

D

Oil in water

Text Solution

Verified by Experts

The correct Answer is:
B
Emulsion of oil and water are unstable and they separate into two layers on standing. Non-polar solvent dissolves non-polar solute. So in case of solution of fat in milk, the phase contains the dispersed phase throughout.
