Explain the following giving examples.

(a) Saturated solution

(b) Pure substance

(c) colloid

(d) Suspension

(a) At any temperature, the solution that has dissolved as much solute as it is capable of dissolving is called as a saturated solution.

Examples: Drinking Beverages, a large amount of sugar dissolved in water.

(b) A pure substance is a substance that consists on only one type of particle in it. A pure solution should not contain any other particles in it.

Examples: Iron, Water, Nitrogen (N₂).

(c) Colloid is a heterogeneous solution in which the particles are partially dissolved. The particles in the colloidal solution cannot be seen using naked eyes but, it can scatter light particles when light is made to pass through it.

Example: Milk, Smoke.

(d) A suspension is a heterogeneous solution that contains particles that can be seen through naked eyes.

Example: Mud Water, chalk water.
