Question

State four conditions for the formation of solution.

Answer 1

Solution- When a solute is dissolved completely into a solvent to form a homogeneous mixture is called a solution.

Solvent - The liquid in which another substance (solute) is dissolved.

Solute - The substance that is dissolved in a solvent.

The four essential conditions for the formation of a solution are -

1. Number of substances -

There should be a minimum of two substances that are readily soluble in each other. The substance in greater quantity is called a solvent and the substance in lesser quantity is called a solute.

2. Mixing -

The solution should be stirred continuously to ensure the proper dissolving of a solute in the solvent.

3. State of solute -

• The solute if solid should be in the form of fine powder to dissolve it easily.
• If the solute is liquid then it should be properly mixed with a solvent.
• If the solute is gas then it should be passed through a delivery tube while keeping the container covered.

4. Temperature -

The temperature of the solvent should be higher than that of the solute as it increases the solubility of the solute in the solvent.
