Calculate the equivalent weight of ferrous sulphate (a) as salt and (b) as reductant. 

Explanation

Formula weight of ferrus sulphate.
`FeSO_(4)=56+32+64=152`
(a) As salt, number of electrons transferred in the formation of salt is 2.
Equivalent weight `=(152)/(2)=76`
(b) As reductant, number of electrons transferred
`Fe^(2+) to Fe^(3+) ` is 1
Equivalent weight =152
