Does the solubility of a substance change with temperature? Explain with the help of an example.

Yes, the solubility of a substance increase with an increase in temperature.

For example,

1. Take approximately 50 mL of water in a beaker.

2. Add sugar in the beaker with continuous stirring.

3. When no more sugar can be dissolved, heat the contents of the beaker. The temperature of the solution is brought to 40°C.

4. Start adding sugar again until it doesn’t dissolve in water anymore. The amount of sugar that has been added is calculated and recorded.

5. Steps 3 and 4 are again repeated at 60°C, 80°C, and 100°C and the results are recorded.

The results show that as the temperature of the water increases, the amount of salt dissolving in the solution is also higher.
