Dissolution and Solubility Concepts

Front

What happens when you mix a sugar cube into water?

Back

The sugar cube will dissolve into water.

Front

How can you decrease the concentration of sugar in tea if you added too much?

Back

By dilution.

Front

What term describes a substance that can dissolve in water?

Back

Soluble.

Front

Which dissolves faster in water: sugar cubes or granulated sugar?

Back

Granulated sugar.

Front

What is a saturated solution?

Back

A solution that contains excess solute that cannot dissolve in the solvent.

Front

How can you dissolve more solute in a saturated solution?

Back

By increasing the temperature of the solvent.

Front

What is solubility?

Back

The maximum amount of solute that can dissolve in a given amount of solvent at a specific temperature.

Front

What is the effect of temperature on the solubility of most solids in liquids?

Back

Generally, the solubility of most solids increases with an increase in temperature.

Front

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

Back

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

Front

What is the role of agitation (stirring) in the dissolution process?

Back

Agitation increases the rate of dissolution by helping to disperse the solute particles throughout the solvent.
