Solubility Curve

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 unsaturated?

Back

It means that more solute can still be dissolved in the solvent at a given temperature.

Front

What does it mean if a solution is saturated?

Back

It means that the maximum amount of solute has been dissolved in the solvent at a given temperature.

Front

What does it mean if a solution is supersaturated?

Back

It means that the solution contains more solute than it can normally hold at a given temperature, often achieved by heating.

Front

What is the solubility of KNO₃ at 80°C?

Back

KNO₃ has a high solubility at 80°C, allowing significant amounts to dissolve.

Front

How does temperature affect solubility?

Back

Generally, as temperature increases, the solubility of solids in liquids increases.

Front

What is the solubility of NaCl at 60°C?

Back

NaCl has a specific solubility value at 60°C, which can be compared to other salts.

Front

What is the solubility of K₂Cr₂O₇ at 60°C?

Back

K₂Cr₂O₇ has a specific solubility value at 60°C, which can be compared to NaCl.

Front

What happens to the solubility of KCl as temperature increases?

Back

The solubility of KCl generally increases with temperature.

Front

What is the highest solubility salt at 20°C among CaCl₃, NaNO₃, KCl, and KNO₃?

Back

NaNO₃ has the highest solubility at 20°C.
