Question

the particle size of substance'A'present in water is 200nm what is the nature of solution

Answer 1

colloidal solution.it forms a colloidal solutions

Answer 2

Answer: colloid

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 2 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.

As the particle size is give to be 200 nm, which lies between the range of 2 to 1000 nm, it must be a colloidal solution.
