Solutions Review

A substance doing the dissolving, usually the part of a solution present in the larger amount.

• solvent

• solution

• solute

• solubility

A substance being dissolved, usually the part of the solution in the lesser amount.

• solvent

• solubility

• solute

• concentration

The ability of a substance to dissolve in a solvent.

• solution

• solute

• concentration

• solubility

Describes how much solute has been dissolved in a solution and is expressed in terms of molarity.

• conductivity

• concentration

• solute

• solubility curve

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

• saturated

• supersaturated

• unsaturated

• agitation

A solution in which more solute can be added and dissolved. It is below the maximum amount of solute.

• saturated

• neutral

• unsaturated

• supersaturated

A solution that contains more of the dissolved solute than could be dissolved by the solvent under normal conditions. Increasing temperature or pressure can increase the maximum possible solute dissolved in a solvent.

• saturated

• supersaturated

• unsaturated

• concentration

A graph that compares the amount of solute that will dissolved in a given amount of solvent at various temperatures.

• solubility curve

• surface area

• pH scale

• direct variation

A factor that affects solubility by moving the molecules of the solute and solvent around to cause more collisions to increase the rate of solubility. Ex: stirring.

• indicator

• agitation

• temperature

• surface area

The solubility graph shows the amounts of four substances that will dissolve in 100 grams of water at various temperatures.

Which substance has 80 grams of solute dissolved in 100 grams of water at 50^OC?

• Potassium Bromide

• Potassium Chloride

• Ammonium Chloride

• Lithium Hydroxide
