Solubility Curves for Sugar and Salt

Front

What is solubility?

Back

Solubility is the ability of a substance (solute) to dissolve in a solvent at a given temperature and pressure.

Front

What factors affect the solubility of a solid in a liquid?

Back

Temperature, stirring, and the amount of solute can affect solubility.

Front

How does temperature affect solubility?

Back

Generally, increasing the temperature increases the solubility of solid solutes in liquids.

Front

What is a solubility curve?

Back

A solubility curve is a graph that shows the relationship between the solubility of a substance and temperature.

Front

What does it mean if a solution is saturated?

Back

A saturated solution contains the maximum amount of solute that can dissolve at a given temperature.

Front

What is an unsaturated solution?

Back

An unsaturated solution is one that can still dissolve more solute 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 can you identify a saturated solution on a solubility curve?

Back

A point on the curve represents a saturated solution; any point below the curve is unsaturated.

Front

What happens to solubility of sugar in water as temperature increases?

Back

The solubility of sugar in water generally increases as the temperature increases.

Front

Which is more soluble in water, salt or sugar?

Back

Sugar is generally more soluble in water than salt.
