Expert Answer:

Dear Student
 
Normality :A normal is one gram equivalent of a solute per liter of solution. The definition of a gram equivalent varies depending on the type of chemical reaction that is discussed in integers — it can refer to equations, bases, redox species, and ions that will precipitate and also isotopes.

For example, hydrowchloric acid (HCl) is a monoprotic acid and thus has 1 mol = 1 gram equivalent. One liter of 1 M aqueous solution of HCl acid contains 36.5 grams HCl. It is called 1 N (one normal) solution of HCl. It is given by the folloing formula:
