The equivalent weight of iron in Fe_(2)O would be:

The equivalent mass of iron in Fe_(2)O_3 would be

The valency of iron in Fe_2O_3 is

(a). What is the equivalent weight of (i) Fe(HC_2O_4)_2

The equivalent weight of iron in ferric chloride is ( At.wt. of Fe = 55.8) -

In a reaction, the ferrous (Fe^(+ +)) iron is oxidised to ferric (FE^(+ +)) ion. The equivalent weight of the ion in the avbove reaction is equal to

Fe_(2)S_(3) to FeSO_(4)+SO_(2) : in this reaction the equivalent weight of Fe_(2)S_(3) (asuming S in -2 oxidation state) is-
