Solubility Curves

Front

What is a solubility curve?

Back

A graph that shows the relationship between the solubility of a substance and temperature, indicating how much solute can dissolve in a solvent at various temperatures.

Front

Define saturated solution.

Back

A solution in which the maximum amount of solute has been dissolved at a given temperature, and any additional solute will remain undissolved.

Front

What is an unsaturated solution?

Back

A solution that contains less solute than can be dissolved at a given temperature, meaning more solute can still be added.

Front

What is a supersaturated solution?

Back

A solution that contains more solute than can normally dissolve at a given temperature, often achieved by heating the solution and then cooling it.

Front

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

Back

60 ºC.

Front

How many grams of K₂Cr₂O₇ are soluble in 100 g of water at 95 ºC?

Back

75 grams.

Front

What type of solution is 65g of lead (II) nitrate in 100g of water at 30ºC?

Back

Saturated.

Front

If a saturated solution of K₂Cr₂O₇ at 50°C is cooled to 20°C, how much solid precipitates?

Back

19 g.

Front

How much Ce₂(SO₄)₃ is saturated at 40 ºC in 100 g of water?

Back

3 g.

Front

What factors affect solubility?

Back

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