Interpreting Solubility Curves

Front

What is a solubility curve?

Back

A graphical representation showing the amount of solute that can dissolve in a solvent at various temperatures.

Front

What does it mean when 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, often achieved by heating.

Front

How does temperature affect solubility?

Back

Generally, for most solids, solubility increases with temperature, while for gases, solubility decreases.

Front

What is the solubility of KNO3 at 80ºC?

Back

At 80ºC, KNO3 is unsaturated when 20 grams are dissolved in 100 grams of water.

Front

How much NaNO3 is soluble in 100 g of water at 10ºC?

Back

80 grams of NaNO3 are soluble in 100 g of water at 10ºC.

Front

What is the solubility of Ce2(SO4)3 at 80 degrees?

Back

2 grams of Ce2(SO4)3 are saturated at 80 degrees.

Front

What is the solubility of C12H22O11 at 40 degrees?

Back

240 grams of C12H22O11 are saturated at 40 degrees.

Front

What is the significance of a solubility curve?

Back

It helps predict how much solute can dissolve at different temperatures, aiding in solution preparation.
