Question

Which of the following statement are false regarding colloidal solution?

P. Colloidal solutions are homogeneous in nature.

Q. Colloidal particles pass through an ordinary filter paper.

R. Colloidal particles can be seen with naked eyes.

S. Colloidal particles do not settle under gravity.

• A. P and R
• B. P and S
• C. Q and R
• D. R and S

Answer 1

The correct option is A P and R

Colloids are relatively stable in nature. The particles of the dispersed phase are in a state of continuous motion and remain suspended in the solution.
Colloids require specialized filters known as ultrafilters for filtration.
Colloidal solutions are heterogeneous in nature.
Colloidal particles do not settle under gravity and they can't be seen with naked eyes.

Hence, option $A$ selects the false statements about colloids.
