Question

Define the following terms:

(a) Solvent

(b) Solution

(c) Solute

(d) Saturated solution

(e) Solubility of solution

Answer 1

(a)Solvent: It is the substance that is present in large amounts in a solution. The liquid in which a solute substance will dissolve is known as the solvent.

• In the example of sugar in water, water is a solvent.

(b)Solution: These are homogeneous mixtures of two or more than two components.

• Homogeneous means the uniformity of composition and properties is the same throughout the mixture.
• When a solid substance is dissolved in a solution it results in the formation of liquid solutions.
• Sugar in water(${\mathrm{H}}_2\mathrm{O}$) is an example of a solid in a liquid solution.

(c) Solute: It is the substance that is present in small amounts in a solution. The solid substance that will dissolve in a liquid is known as the solute.

• In the example of sugar in water, sugar is solute.

(d) Saturated solution: It is the type of solution in which no more solute can be added at any given temperature.

• For example, In saturated solutions of sugar in water, no more sugar can be added.

(e) Solubility of solution: The maximum amount of solute that can dissolve in a known quantity of solvent at a certain temperature is its solubility.
