Dear Student,

Equivalent mass= Molecular weightChange in oxidation no
 of Mn                             Oxidation state of Mn in MnSO4 = +2Oxidation state of Mn in Mn2O3= +3Therefore, change in oxidation state of Mn = 3-2=1Now, Oxidation state of Mn in MnO2= +4Therefore, change in oxidation state of Mn = 4-2=2Oxidation state of Mn in MnO4-= +7Therefore, change in oxidation state of Mn = 7-2=5Oxidation state of Mn in MnO42-= +6Therefore, change in oxidation state of Mn = 6-2=4Therefore, the correct answer will be MnO2 because, Equivalent weight=Molaecular weight2Hence, correct answer is (2)

The equivalent weight of MnSO4 is equal to its molecular weight when it is converted to (1)Mn2O3 (2) MnO2 (3) MnO4-(4) MnO42-
