What are the molarity and the normality of a solution made
bydissolving 25g of of citric acid(c6
h5o7 h3 ,a triprotic acid) in
enough water tomake 750 ml of solution?

Explanation:

It is known that molarity is the number of moles present in a liter of solution.

Mathematically,    Molarity =

Hence, calculate the molarity of given solution as follows.

     Molarity of citric acid =

                                 =

                                 = 0.173 M

As citric acid is a triprotic acid so, upon dissociation it gives three hydrogen ions.

          Normality = Molarity × no. of hydrogen or hydroxide ions

                            = 0.173 × 3

                            = 0.519 N

Thus, we can conclude that molarity of given solution is 0.173 and its normality is 0.519 N.
