Question
State four conditions for the formation of solution?
✓

Answer

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.
