    Molarity of a given orthophosphoric acid solution is 3 M. It's normality is

    A) 9 N                                        

    B) 0.3 N

    C) 3 N                                        

    D) 1 N

    Correct Answer: A

    Solution :

    Orthophosphoric acid \[({{H}_{3}}P{{O}_{4}})\] is a tribasic acid. \[\because \] Normality = Molarity x basicity \[\therefore \] Normality \[=3\,M\times 3\]                          = 9 N
