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 a supersaturated solution.

Back

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

Front

What factors affect solubility?

Back

Temperature, pressure (for gases), and the nature of the solute and solvent.

Front

At what temperature does the solubility of NaCl match that of K2Cr2O7?

Back

60 ºC.

Front

Which solute is least soluble at 90 ºC: SO2, KClO3, KI, or HCl?

Back

SO2.

Front

How many grams of NaCl are needed to saturate a solution if 25 grams are already dissolved in 100 mL of water at 60 ºC?

Back

13 grams.

Front

What is the solubility of K2Cr2O7 in 100 g of water at 90 ºC?

Back

70 grams.

Front

What is the significance of a solubility curve in chemistry?

Back

It helps predict how much solute can dissolve in a solvent at various temperatures.
