Henry's Law

Front

What is Henry's Law?

Back

Henry's Law states that the solubility of a gas in a liquid is directly proportional to the pressure of that gas above the liquid.

Front

Define an unsaturated solution.

Back

An unsaturated solution is one where more solute can still be dissolved at the given temperature.

Front

What is a saturated solution?

Back

A saturated solution is one that contains as much solute as it can hold at a given temperature.

Front

What happens to gas solubility when pressure increases?

Back

According to Henry's Law, the solubility of a gas in a liquid increases as the pressure of the gas above the liquid increases.

Front

How does temperature affect the solubility of gases?

Back

Increasing temperature generally decreases the solubility of gases in liquids.

Front

What is a supersaturated solution?

Back

A supersaturated solution contains more solute than can normally be dissolved at a given temperature.

Front

What does it mean to dilute a solution?

Back

To dilute a solution means to lower the concentration of solute per solvent.

Front

What is the relationship between solubility and temperature for solids?

Back

For most solids, solubility increases with an increase in temperature.

Front

What is the effect of increasing temperature on the solubility of solids?

Back

Increasing temperature typically increases the solubility of solid solutes in liquids.

Front

What is the effect of increasing pressure on the solubility of solids?

Back

Increasing pressure has little to no effect on the solubility of solids in liquids.
