Question

In suspension the size of particle is:
A.${\text{1}}{{\text{0}}^{{\text{ - 7}}}}{\text{m or more}}$
B.${\text{1}}{{\text{0}}^{{\text{ - 10}}}}{\text{m or more}}$
C.${\text{1}}{{\text{0}}^6}{\text{m or less}}$
D.${\text{1}}{{\text{0}}^2}{\text{m or more}}$

Answer 1

Hint:Suspension is basically a heterogeneous mixture of solute and solvent in which the solute particles float freely around the solvent or the medium present. The size of suspension particles is large as compared to colloid particles.

Complete answer:
Suspension solution: A heterogeneous mixture in which the solute particles do not dissolve in solvent particles is known as suspension solution. The solute particles remain suspended in the bulk of solvent particles and therefore the solution is named as suspension. The solute particles freely float in the present medium.
The suspended particles show no attraction with solvent particles and if the solution is left undisturbed for a specific time the suspended particles settle down at the bottom of the vessel.
The most common example of suspension used in chemistry is dispersion of solid particles in liquid (sand in water). And this is also a big difference between the colloids and suspension, as the particle size in colloid is very small and hence if the colloid is left undisturbed for some time the suspended particles do not settle down while in suspension the solute particles or the solid particles settle down when it is kept undisturbed.
Suspensions are also unstable from the thermodynamic point of view.
In suspension the size of particles is quite larger, $100{\text{nm}}$(${10^{ - 7}}{\text{m}}$) or more.

So, option (A) is correct.

Note:
The gravitational force works well in heterogeneous mixtures or we can say suspension. The suspension particles are quite larger than particles of solution so they settle down or the gravity pulls them down in the dispersion medium.
