Solution

A homogeneous mixture.

Solute

The substance being dissolved.

Solvent

The substance doing the dissolving.

Dilute Solution

A solution containing a relatively small amount of solute dissolved.

Concentrated Solution

A solution containing a relatively large amount of solute dissolved.

Soluble

Compounds that dissolve in water.

Insoluble

Compounds that do not dissolve completely in water; they are also known as precipitates.

Molarity (M)

Moles of solute divided by liters of solution.

When a solute is added to water

The freezing point decreases and the boiling point increases

Higher concentration of solute in water

Lower freezing point higher boiling point

Solutes dissolve faster by

Larger surface area, stirring, higher pressure, adding more solvent, heating the solution
