Question

Classify the following as solutions, colloids and suspension. Write their properties.

a. b. c.

Accepted Answer

Types of substance Properties

a. Muddy water
Suspension In suspension, the size of particles is usually more than $1000 nm$ . So, the particles of suspension can be seen with naked eyes. A suspension is a heterogeneous mixture in which the solid particles are spread throughout the liquid without dissolving in it.

b. Milk
Colloid A colloid is a heterogeneous mixture in which solute particles neither dissolve nor settle down at the bottom. It is translucent and the particles can be seen by microscope. The size of solute particles in colloids is intermediate between those in true solutions and suspensions. The size of particles lies between $1 - 1000 nm$ .
.

c. Copper sulphate solution
Solution The true solution is a homogeneous mixture of a solute and a solvent. The size of particles in the true solution is less than $1 nm$ . The particles cannot be seen through the naked eye or a microscope. A solution is clear and transparent in appearance. The particles of the solution easily pass through the filter paper and therefore, it is impossible to separate them.
