Solute

Front

What happens to the solubility of a solute when the temperature of the solvent increases?

Back

Generally, the solubility of most solids increases with temperature.

Front

What is a solution?

Back

A homogeneous mixture of two or more substances.

Front

What is miscibility?

Back

The ability of two substances to mix in all proportions without separating.

Front

What is the effect of stirring on the rate of dissolution?

Back

Stirring increases the rate at which a solute dissolves in a solvent.

Front

What is a solubility curve?

Back

A graph that shows the relationship between solubility and temperature for a specific solute.

Front

What is the difference between a saturated solution and an unsaturated solution?

Back

A saturated solution contains the maximum amount of solute that can dissolve at a given temperature, while an unsaturated solution can still dissolve more solute.
