Learn the basics about solubility curves as a part of the overall properties of matter topic.

Solubility curves are a graphical representation of the solubility of a certain salt over a temperature range. 

Copper (II) sulfate is a lot more soluble than potassium sulfate, so it has a higher solubility in water. 

This is actually a physical property of a substance – much like boiling points and melting points.

The solubility of a salt in water is usually measured as grams of salt per 100g of water. 

Solubility usually increases with increasing temperature. This observation is only applicable to a solid dissolving in a liquid - the reverse is observed when dissolving a gas in a liquid.

We can plot solubility as a function of temperature to give a solubility curve.
