Normality

 Normality is defined as the number of gram-equivalent weights of solute per litre of solution, and is denoted by N. This designation is useful for solutions of acids and bases. One gram-equivalent weight of an acid is the quantity of the acid that can denote one mole of hydrogen ions to a base; one gram-equivalent of a base is that amount which can accept one mole of hydrogen ions. For a monoprotic acid such as acetic acid, which yields one mole of hydrogen ions upon complete dissociation, the gram-equivalent weight is equal to the molecular weight.
