NormalityWhen 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 the lesson on acidbase titrations and give it just a cursory mention in this lesson. For that reason you can ignore objectives 69 and examples 1317 in your workbook for this lesson. 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.
Hopefully, this gives you an idea of the nature and value of normality and its relationship to molarity. As mentioned earlier, it will be covered in more detail in the lesson involving acidbase titrations.
