Normality

Normality When you need to compare solutions on the basis of concentration of specific ions or the amount of charge that the ions have, a different measure of concentration can be very useful. It is called normality. We will deal with normality more completely in  acid-base titration.The normality of a solution is simply a multiple of the molarity of the solution. Generally, the normality of a solution is just one, two or three times the molarity. In rare cases it can be four, five, six or even seven times as much. The symbol for normality is N or N.  CaCl2 Ca2+ + 2 Cl- 1 M CaCl2 = 2 N CaCl2
