Colloidal particles can be separated by using:
Correct answer: D. Extremely fine filter paper
- A. Ordinary filter paper
- B. Coarse filter paper
- C. Fine Filter paper
- D. Extremely fine filter paper
Explanation
Colloidal particles are small solid particles that are suspended in a fluid phase. Their size range is typically between 10nm. Colloidal particles can be separated by a centrifugation method using fine filter.

About Solutions and Colloids
Solutions are described using molarity, molality, normality, mole fraction, percentage concentration and parts per million. Coverage also includes vapour-pressure lowering, boiling-point elevation, freezing-point depression and osmotic pressure, then distinguishes true solutions, colloids and suspensions by particle size, stability, light scattering and settling.
