Solubility Curves 10Q

Front

What is a solubility curve?

Back

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

Define 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, for most solids, solubility increases with temperature.

Front

What is the solubility of NaBr at 70 degrees Celsius?

Back

120 grams per 100 grams of water.

Front

At what temperature can you fully dissolve 140g of NaNO3?

Back

73 degrees Celsius.

Front

What type of solution is 60g NaNO3 at 40ºC in 100g H2O?

Back

Unsaturated.

Front

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

Back

The excess solute will not dissolve and will remain as a solid.

Front

What is the solubility of KClO3 at 80ºC?

Back

It varies, but if 20g is dissolved in 100g of water, the solution is unsaturated.
