Solubility Curves

Front

What is a solubility curve?

Back

A graphical representation showing the relationship between 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.

Front

Which solute does not increase in solubility with temperature: NH3, NaNO3, KNO3, or NaCl?

Back

NH3 (ammonia) does not increase in solubility as temperature rises.

Front

What happens to the solubility of most solid solutes as temperature increases?

Back

Most solid solutes increase in solubility as temperature increases.

Front

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

Back

73ºC is the temperature at which you can fully dissolve 140g of NaNO3.

Front

What type of solution is formed when 50g of KCl is dissolved in 100g of water at 50ºC?

Back

The solution is supersaturated.

Front

Which of the following is most likely a gas: KNO3, NaNO3, KCl, or Ce2(SO4)3?

Back

Ce2(SO4)3 is most likely a gas.

Front

What is the effect of temperature on the solubility of gases in liquids?

Back

Generally, the solubility of gases decreases as temperature increases.
