Determine the equlavent weights of the underlined compounds in the following two reactions:
`FeSO_(4)+underline (KMnO_(4))+H_(2)SO_(4)toK_(2)SO_(4)+MnSO_(4)+Fe_(2)(SO_(4))_(3)+H_(2)O`

Text Solution

Verified by Experts

`overset(+7)(KMnO_(2))tooverset(+2)(MnSO_(4))`: In this reaction decrease in oxidation of Mn =(7-2)=S unit.
`therefore` Equivalent weight of `MnO_(2)`
`("Molecular weight "of KMnO_(4))/("Change in oxdation number ")=(158)/(5)=31.6`
