Which of the following will increase the solubility of a gas in a liquid? Select allthat apply.

• Increasing pressure

• Decreasing pressure

• Increasing temperature

• Decreasing temperature

Solubility is:

• How much of a solute is dissolved in a solvent

• The maximum amount of a solute that can be dissolved in a solvent

• A special type of solution

Concentration is:

• How much of a solute is dissolved in a solvent

• The maximum amount of a solute that can be dissolved in a solvent

• A special type of solution

A dilute solution is:

• Any solution with a solid dissolved in a liquid

• Any solution with a liquid dissolved in a liquid

• Any solution with a gas dissolved in a liquid

• A solution with only a small amount of solute compared to solvent

An unsaturated solution:

• can still dissolve more solute.

• has the maximum possible amount of solute.

• has more solute that the solubility allows.
