2023-24 Solutions and Solubility Curves Review

Front

What are the factors that affect solubility?

Back

Temperature, pressure, and the nature of the solute and solvent.

Front

How many grams of K2Cr2O7 are soluble in 100 g of water at 95 ºC?

Back

75 grams.

Front

What conclusion can be made using this solubility curve?

Back

Increasing temperatures usually increases solubility.

Front

Define saturated solution.

Back

A solution in which the maximum amount of solute has been dissolved in the solvent.

Front

What are pure substances?

Back

Not mixtures.

Front

What is a solubility curve?

Back

A graph that shows the relationship between solubility and temperature for a specific solute.

Front

What is the effect of temperature on solubility for most solids?

Back

Generally, solubility increases with an increase in temperature.

Front

What is the effect of pressure on the solubility of gases?

Back

Increasing pressure increases the solubility of gases in liquids.

Front

What is a supersaturated solution?

Back

A solution that contains more solute than can normally dissolve at a given temperature.

Front

What is the difference between a saturated and an unsaturated solution?

Back

A saturated solution contains the maximum amount of solute, while an unsaturated solution can still dissolve more solute.
