    Normality and molarity changes with temperature because they involve volumes. The normality of 0.3 M. phosphoric acid, \[{{H}_{3}}P{{O}_{4}}\] is

    A)  0, 9                             

    B)  0.1                 

    C)  0.3                              

    D)  0.6

    Correct Answer: D

    Solution :

    Since, \[{{H}_{3}}P{{O}_{3}}\] is a diprotic acid \[\therefore \,\,\,\,\,\,\,\,\,n=2\,\,\,\,\,\Rightarrow \,\,\,\,N=M\,\,\times \,\,2\] \[N=2\times 0.3=0.6\]
