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 substance is soluble?

Back

It means that the substance can dissolve in a solvent, such as water, to form a solution.

Back

A solution in which no more solute can dissolve at a given temperature.

Front

What is the significance of a solubility graph?

Back

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