Reading Solubility Graphs

Front

What is solubility?

Back

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

Front

What is a solute?

Back

The substance that is dissolved in a solution, e.g., salt in saltwater.

Front

What is a solvent?

Back

The substance that dissolves the solute, e.g., water in saltwater.

Front

What does a saturated solution mean?

Back

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

Front

What is an unsaturated solution?

Back

A solution that can still dissolve more solute at a given temperature.

Front

What is a supersaturated solution?

Back

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

Front

How does temperature affect solubility?

Back

Generally, as temperature increases, the solubility of solids in liquids increases.

Front

What is the solubility graph?

Back

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

Front

At what temperature can you fully dissolve 60g of KNO3?

Back

37°C.

Front

What happens when a saturated solution is cooled?

Back

Some solute may crystallize out of the solution.
