ICSE Class 8 Answered

The solubility of a solute in a particular solvent at a particular temperature is the maximum amount of a solute in gram

which can be dissolved in 100 gram of a solvent at that temperature.

Factors Affecting Solubility

• Size of solute particles: Smaller the size of solute particles, greater will be the solubility of that solute.
• Stirring: It brings more of the solvent in contact with the solute, thus increasing the rate of the formation of the solution.
• Temperature: Solubility of a solid solute increases with increase in temperature.

                            Solubility of a gas solute decreases with increase in temperature.

                            Solubility of a gas solute increases with increase in pressure.
