Front

What is a solution?

Back

A solution is a homogeneous mixture formed when a solute dissolves in a solvent.

Front

What factors affect the rate of dissolving?

Back

The rate of dissolving can be affected by temperature, stirring, and the size of the solute particles.

Front

How does temperature affect dissolving?

Back

Increasing the temperature usually increases the rate at which a solute dissolves.

Front

What is saturation?

Back

Saturation occurs when a solvent can no longer dissolve any more solute at a given temperature.

Front

What is a concentrated solution?

Back

A concentrated solution has a large amount of solute compared to the amount of solvent.

Front

What is a dilute solution?

Back

A dilute solution has a small amount of solute compared to the amount of solvent.

Front

What is an example of a soluble substance?

Back

Sugar is an example of a soluble substance that dissolves in water.
