Reading Solubility Graphs

Front

What is a solubility graph?

Back

A solubility graph is a visual representation that shows how the solubility of a substance changes with temperature.

Front

What does it mean for a solution to be saturated?

Back

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

Front

What is the solubility of KClO3 at 70 ºC?

Back

Approximately 60 grams per 100 grams of water.

Front

How do you determine if a solution is unsaturated?

Back

A solution is unsaturated if it can still dissolve more solute at a given temperature.

Front

What is the significance of temperature in solubility?

Back

Temperature affects the solubility of most solids; generally, solubility increases with temperature.

Front

What is a supersaturated solution?

Back

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

Front

How many grams of KNO3 are needed for a saturated solution at 40 ºC?

Back

53 grams.

Front

What happens when you add more solute to a saturated solution?

Back

The excess solute will not dissolve and will remain undissolved at the bottom.

Front

What is the solubility of SO2 at 50 ºC?

Back

5 grams per 100 grams of water.

Front

How can you identify a saturated solution visually?

Back

A saturated solution may have undissolved solute visible at the bottom of the container.
