2021 - Solutions & Solubility

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

Which salt is least soluble at 0 ºC?

Back

KClO3 is the least soluble salt at 0 ºC.

Front

What is the solute when sugar is dissolved in water?

Back

The solute is sugar.

Front

What does a solubility curve show?

Back

A solubility curve shows how solubility changes with temperature.

Front

What is an unsaturated solution?

Back

An unsaturated solution contains less solute than can dissolve at a given temperature.

Front

What is a supersaturated solution?

Back

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

Front

How does temperature affect solubility?

Back

Generally, solubility increases as temperature increases for most solids.

Front

What is the definition of solubility?

Back

Solubility is the maximum amount of solute that can dissolve in a given amount of solvent at a specific temperature.

Front

What happens to solubility as temperature decreases?

Back

Solubility generally decreases as temperature decreases for most solids.

Front

What is the difference between a solute and a solvent?

Back

A solute is the substance that is dissolved, while a solvent is the substance that does the dissolving.
