Question

The equivalent weight of H2SO4 in the reaction

Na2CO3+H2SO4Na2SO4+CO2+H2O is:

Moderate
Solution

Reaction :

Na2CO3+H2SO4Na2SO4+CO2+H2O

           2 H-atoms         no. H atom

     No. of replaceable H-atoms = 2-0=2  

    Eq. wt. of H2SO4= Mol. wt. of H2SO4 no. of replaceable H-atoms 

                                        =(2×1)+32+(4×16)2=49
