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 not dissolve.

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

How does temperature affect solubility?

Back

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

Front

What is the solubility of NaCl in water at 60°C?

Back

Approximately 39 grams of NaCl can dissolve in 100 mL of water at 60°C.

Front

If 20 grams of KClO3 are dissolved in 100 grams of water at 80°C, what type of solution is formed?

Back

The solution is unsaturated.

Front

What is the solubility of KCl at 70°C?

Back

At 70°C, the solubility of KCl is approximately 56 grams per 100 grams of water.

Front

What does it mean if a solution is described as supersaturated?

Back

It means that the solution contains more dissolved solute than it would under normal circumstances at that temperature.

Front

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

Back

You can fully dissolve 140g of NaNO3 at approximately 73°C.
