Answer : The equivalent weight of will be 158 g/eq.
Explanation :
The given balanced reaction is,
The oxidation number of Mn in ,
(+1) + (x) + 4(-2)=0
x = (+7)
The oxidation number of Mn in ,
2(+1) + (x) + 4(-2)=0
x = (+6)
The change in oxidation number = 1
Formula used :
The molecular weight of = 158 g/mole
Therefore, the equivalent weight of will be 158 g/eq.
