Question

If you have a saturated solution at equilibrium, what changes could you make to increase the solubility of the compound?.

Answer 1

1. A colloid may look homogeneous from the outside, but is a heterogeneous mixture.

2. Diameter of the particles of colloids ranges between 1-100 nm.

3. Tyndall effect is observed in colloids if a light beam passes through it. Solution with large solute particles, which are intermediate in diameter between those in correct solutions and those in suspensions are defined as colloids.

Explanation

Characteristics of colloids:

The size of particles in a colloid is greater than those in a correct solution but lesser than those in a suspension. The diameter of a colloid particle lies between 1 nm and 100 nm.

A colloid is a heterogeneous mixture of dispersed phase and dispersed medium. For example, butter is a colloid in which tiny fat droplets stay dispersed in a liquid to form an emulsion.

Special techniques like centrifugation apply to separate colloid particles. The filtration process is useless in separating the constituents of a colloid.

The particles of a colloid are so large that they can scatter a beam of light passing through it. This is known as Tyndall effect.

Colloid particles do not aggregate at the bottom of the vessel if the solution is left undisturbed.
