A:A can of warm soda will fizz more because increasing the temperature decreases the solubility of a gas. Therefore,
less carbon dioxide can remain dissolved in warm soda than in cold soda.
Summary
- Solubility is the amount of solute that can dissolve in a given amount of solvent at a given temperature. Some
solutes have greater solubility than others. - Temperature affects the solubility of solutes in all three states. Pressure also affects the solubility of gases.
Vocabulary
- solubility: Amount of solute that can dissolve in a given amount of solvent at a given temperature.
