It is often necessary to prepare a dilute solution from a more concentrated solution rather than starting from a solid and just dissolving it then adding water. This technique is called serial dilution.

Unshared, or lone, electron pairs play an important role in determining the chemical and physical properties of organic compounds. thus, it is important to know which atoms carry unshared pairs.
