Front

What is a solute?

Back

The substance that is dissolved in a solution.

Front

What is a solvent?

Back

The substance that dissolves the solute in a solution.

Front

What does it mean for a solution to be saturated?

Back

A solution that has dissolved the maximum amount of solute at a given temperature and pressure.

Front

What is a supersaturated solution?

Back

A solution that contains more solute than it can theoretically hold at a given temperature.

Front

What does 'like dissolves like' mean?

Back

Polar solutes dissolve in polar solvents, and non-polar solutes dissolve in non-polar solvents.

Front

What is a heterogeneous mixture?

Back

A mixture where the components are not uniformly distributed and can be visibly distinguished.

Front

What is a homogeneous mixture?

Back

A mixture where the components are uniformly distributed and cannot be visibly distinguished.

Front

How does temperature affect the rate of dissolution?

Back

Increasing the temperature generally increases the rate of dissolution.

Front

What effect does stirring have on dissolution?

Back

Stirring increases the rate of dissolution by distributing the solute particles throughout the solvent.
