Question

Crystalloids differ from colloids mainly in respect of :

• A. electrical behaviour
• B. particle nature
• C. particle size
• D. solubility

Answer 1

The correct option is C particle size

Colloids :

A colloid is a heterogeneous system in which one substance is dispersed (dispersed phase) as very fine particles in another substance called dispersion medium. The solution and colloid essentially differ from one

another by particle size.

Crystalloids are aqueous solutions of mineral salts or other water-soluble molecules. Colloids contain larger insoluble molecules, such as gelatin. Blood is a colloid. So, they mainly differ in particle size.
