Question

The size of solute particles is of the order of ${10}^{-8}cm$ or less in

• A. solution
• B. colloid
• C. suspension
• D. none of these

Answer 1

The correct option is A

solution

The explanation for the right answer:

Option A: Solution

• The solution is a homogeneous mixture in which the size of particles dissolved is less than ${10}^{-8}cm$ or $0.1nm$.
• It may be less then ${10}^{-8}cm$ or $0.1nm$
• So, option A is the right answer.

The explanations for the wrong answers:

Option B: Colloid

• The particle size of colloids typically ranges from $1nanometer$ to $1micrometer$.
• So, option B is the wrong answer.

Option C: Suspension

• The particles of a suspension are of a size greater than 100nm.
• So, option C is the wrong answer.

Conclusion:

So, the size of solute particles is of the order of ${10}^{-8}cm$ or less it is a true solution

Therefore, the right answer is option A Solution.
