Effect of Temperature on Solubility

Have you ever wondered why a cold soda tastes better than a warm one? The cold one maintains the silky, bubbly taste, while the warm soda just feels flat. The silky taste is caused by the amount of carbon dioxide dissolved in the soda solution. When the temperature increases, and more heat is added to the system, the carbon dioxide gains energy and escapes from the solvent. This decreases the solubility of the gas.

When we dissolve a solid into a liquid, an opposite effect occurs. Now when the amount of heat increases, the liquid will gain energy, and will be able to break the bonds of the solid better. So when dissolving salt into boiling water, more salt will dissolve compared to water of room temperature.

Creative Application

1. How does a decrease in temperature affect the solubility of a gas into a liquid? a solid into a liquid? Why?

2. How come a gas dissolving into a liquid and a solid dissolving into a liquid are affected differently by changes in temperature?

3. Is the relationship between temperature and solubility linear? (Hint: look up “solubility curve”)
