Interpreting Solubility Curves

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 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 the solubility of most solids?

Back

For most solids, solubility increases as temperature increases.

Front

Which substance is most soluble at 0 ºC: KI, NaNO3, NaCl, or Ce2(SO4)3?

Back

NaNO3 is the most soluble at 0 ºC.

Front

What happens to the solubility of NH3 as temperature rises?

Back

The solubility of NH3 decreases as temperature rises.

Front

What is the solubility of KCl at 70ºC if 60g is dissolved in 100g of water?

Back

The solution is supersaturated.

Front

If 50 grams of KCl is dissolved in 100 grams of water at 50 ºC, how is the solution described?

Back

The solution is supersaturated.

Front

What is the solubility status of KNO3 when 20 grams is dissolved in 100 grams of water at 80 ºC?

Back

The solution is unsaturated.
