Normality is usually used in acid-base reactions and is a means of expressing the number of reactive units that are present in a solution.
In acid-base reactions, a reactive unit is simply a proton,
When you have something like hydrochloric acid,
This happens because you get 1 mole of reactive units, in this case
For a diprotic acid like
SInce 1 mole of sulfuric acid produces 2 moles of
Likewise, when you have a 0.1 M
In this case, the reactive unit is
So, as a conclusion, the normality of a solution depends entirely on what that solution contains; when you have 1 mole of reactive units produced by every 1 mole of a compound, then a 0.1 M solution is also a 0.1 N solution.
Normality was also used for redox reactions and precipitation reactions, the reactive units being the electrons lost or gained for the former, and the number of ions that will precipitate, for the latter.
