प्रश्न
Give three factors which affect the solubility of a solid solute in a solvent.
उत्तर
The rate of dissolution or rate of solubility of a solid in a liquid depends on the following factors:
- Size of solute particles: The smaller the size of the solute particles, the greater is its total surface area exposed to the solvent. Therefore, the greater is the solubility of that solute.
- Stirring: This brings more of the solvent in contact with the solute and thus increases the rate of formation of solution.
- Temperature: The solubility of a gas in a liquid always decreases with rise in temperature. But the solubility of most solids in water usually increases with rise in temperature.
