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 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 can still dissolve more solute at a given temperature.

Front

What is a supersaturated solution?

Back

A supersaturated solution contains more solute than can normally dissolve at a given temperature.

Front

Which substance is most soluble at 0°C?

Back

NaNO3 is the most soluble at 0°C.

Front

At what temperature does NaCl's solubility match that of K2Cr2O7?

Back

The solubility of NaCl matches that of K2Cr2O7 at 60°C.

Front

What is the solubility of NaNO3 at 20°C?

Back

NaNO3 has the highest solubility at 20°C compared to other common salts.

Front

What happens to solubility as temperature increases?

Back

Generally, the solubility of solids increases with temperature.

Front

What is the solubility of KCl at 50°C?

Back

KCl can form a supersaturated solution at 50°C if more than the normal solubility is dissolved.

Front

What is the significance of a solubility curve?

Back

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