Question

Dipti was asked to prepare three separate mixtures in beakers A, B, and
C, by mixing sugar, chalk powder, and soap powder respectively in water.
What is the order of relative size of solute particles in solutions A, B, and
C?
A. A>B>C
B. C>A>B
C. B>C>A
D. C>B>A

Answer 1

Answer:

C is the correct option in this question

Answer 2

The order of relative size of solute particles in solutions A, B, and C is option C. B>C>A.

To find the order of relative size amongst all options, we need to know about types of solutions.

Types of Solutions:-

• True solution: True solutions are liquid-phase combinations in which the solute and solvent combine properly. So, the size of the solute is very small. A Sugar-water mixture is a true solution.
• Colloids: A colloid is a substance made up of particles that are larger than conventional molecules but not large enough to be seen with the naked eye. Soap powder and water mixture is a colloid.
• Suspension: Suspension is a heterogeneous combination wherein the large-sized particles are spread all through the fluid without dissolving in it. Chalk powder in water is an example.

Hence, we can conclude that Chalk powder will have the largest size followed by soap powder and sugar.
