Interpreting Solubility Curves

Front

What is a solubility curve?

Back

A graphical representation showing 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 supersaturated solution.

Back

A supersaturated solution contains more solute than can normally dissolve at a given temperature, often achieved by heating.

Front

How does temperature affect solubility of solids in water?

Back

Generally, the solubility of most solid solutes increases with an increase in temperature.

Front

What is the solubility of K2Cr2O7 at 95 degrees Celsius?

Back

75 grams per 100 grams of water.
