NORMAL

A normal solution contains one grain equivalent weight of reactant (compound) per. liter of solution. The equivalent weight of an acid is that weight which contains one gram atom of ionizable hydrogen or its chemical equivalent. For example, the equivalent weight of sulfuric acid (H2SO4 is 49 (98 divided by 2 because there are two replaceable hydrogen ions). A one N solution of sulfuric acid would consist of 49 grains of H2SO4 dissolved in enough water to make one liter of solution.
