Question

equivalent mass of MnSO4 ? ​

Answer 1

Answer:

The equivalent weight of MnSO4 is half its molecular weight when it is converted to. If valency is 2, then equivalent weight will be equal to its molecular weight. Thus, when MnSO4 is converted into MnO2, then the valency factor is 2, and the equivalent weight of MnSO4 will be half of its molecular weight

Answer 2

Answer:

net oxidation state of Mn in MnSo4 is Mn+(SO4)=0

so,Mn+(-2)=0 (net charge of SO4=-2)

Mn=2

now net charge of Mn in MnO2=

Mn+(-2)2 (net charge on O=-2

Mn=4

MnSO4-----MnO2

equivalent weight =molecular weight (let M)/change in the oxidation state

equivalent weight=M/(4-2)

=M/2

Thus equivalent weight of MnSO4 is half the molecular weight when it is converted to MnO2
