Question

The diameters of colloidal particles may range from

1 to 100 nm
10 to 100 pm
1 to 100 mm
10 to 100 mm

Answer 1

convert it yourself range is from 1nm to 1mm

Answer 2

Answer: 1 to 100 nm

Explanation:

The solutions are classified into 3 types on the basis of size of the particles.

1) Solution: When the particle size is between 0.1 nm to 1 nm, then the solution is considered as a true solution.

2) Colloid: When the particle size is between 1 to 1000 nm, then the solution is considered as a colloid.

3) Suspension: When the particle size is greater than 1000 nm, then the solution is considered as a suspension.
