Solubility

Front

What is solubility?

Back

Solubility is the ability of a substance (solute) to dissolve in a solvent at a given temperature and pressure.

Front

What is a saturated solution?

Back

A saturated solution is one in which no more solute can dissolve at a given temperature; it is in equilibrium with undissolved solute.

Front

What is an unsaturated solution?

Back

An unsaturated solution is one that 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; it is unstable.

Front

What is the solvent in a solution?

Back

The solvent is the substance that dissolves the solute, typically present in greater amount.

Front

What is the solute in a solution?

Back

The solute is the substance that is dissolved in the solvent.

Front

How does temperature affect solubility?

Back

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

Front

At what temperature do KBr and KNO3 have the same solubility?

Back
