Effect of temperature on solubilityFeatured science projectScience project video

Conclusion

The hypothesis that as the temperature of the water increases, the amount of substance dissolved in the water also increases is proven to be true.

Solubility of a substance in a solvent can be increased or reduced by  adding   another   substance. For example, adding salt in a solution saturated with sugar will enable more sugar to be dissolved in the solution. This technique is used in candy making. .

Also consider

Try to repeat the experiment by using other substances like calcium chloride, potassium permanganate or iron sulfate.

The experiment can also be repeated using different solvents like alcohol or benzene.
