    \[Ca{{(OH)}_{2}}+{{H}_{3}}P{{O}_{4}}\to CaHP{{O}_{4}}+2{{H}_{2}}O\] the equivalent weight of \[{{H}_{3}}P{{O}_{4}}\] in the above reaction is   [Pb. PMT 2004]

    A)                 21          

    B)                 27

    C)                 38          

    D)                 49

    Correct Answer: D

    Solution :

               The equivalent weight of \[{{H}_{3}}P{{O}_{4}}=\frac{\text{molecular weight}}{2}\]                    \[\because \] mole wt of \[{{H}_{3}}P{{O}_{4}}\]= 3 + 31 + 64 = 98                                 \ \[\frac{98}{2}=49\]
