Question

The correct designation representing the particle size is

(a) I = true solution, II= suspension and III= colloid

(b)I = suspension, II= true solution and III= colloid

(c) I = colloid, II= suspension and III= truesolution

(d)I = true solution, II= colloid and III= suspension​

​

Answer 1

Answer:

b is answer

Explanation:

I = suspension, II= true solution and III= colloid

Answer 2

(d)I = true solution, II= colloid and III= suspension​.

• Particles of a true solution are smaller than 1 nm in the diameter &  can't be seen by naked eyes.

• Particles of the colloid are very small and individually seen with naked eyes but these are larger than a particles of true solution.

• Particles of the suspension can seen by naked eye. These are larger than those colloids & true solutions.

• If size of the solute particle is less than that of 1 nm in solution, then it is the true solution. If the size of a solute particles is between the 1 - 100 nm then it is a colloidal solution.

Hence the correct designation of representing the particle size is :

Option D  I = true solution, II= colloid and III= suspension​
