Question

Arrange true solution, colloidal solution, and suspension in the decreasing order of their particle size.

• A. Suspension > Colloid > True solution
• B. Suspension > True solution > Colloid
  
• C. Colloid > Suspension > True solution
  
• D. True solution > Colloidal > Suspension
  

Answer 1

Answer: (A)

• Particles of a true solution are smaller than 1 nm in diameter and cannot be seen by naked eyes.
• Particles of a colloid are too small to be individually seen by naked eyes but larger than particles of true solutions.
• Particles of a suspension can be seen by the naked eye. They are larger than those of colloids and true solutions.
