Compared to making Molar solutions, making Normal solutions can be a bit confusing.
Aqueous solutions of acids and bases are often described in terms of their normality
rather than their molarity. In order to properly make a Normal solution, the worker must
understand the difference between a pure reagent and a diluted reagent.
A "1 Normal" solution (1 N) contains 1 “gram equivalent weight” (gEW) of solute,
topped-off to one liter of solution. The gram equivalent weight is equal to the solute’s
molecular weight, expressed as grams, divided by the valence (n) of the solute:
Equivalent weight
