Question

A homogenous non crystalline substance consisting of large molecules or ultramicroscopic particles of one substance dispersed through a second substance are known as colloids. These colloids are of different types. What are they?

• A. Gel
• B. Emulsions
• C. Sol
• D. All of these

Answer 1

The correct option is D All of these

Sol, gel and emulsions are the different types of colloids. These particles do not settle and they cannot be filtered by ordinary filtration method or by centrifugation method like those in suspension.
The solute and the solvent phase in case of colloid is found as a dispersed phase.
