The equivalent mass of iron in the reaction, 3 Fe + 4 H2O Fe2o3 +4h2
(a) 21
(b) 56
c 42
(d) 10​

Answer 1

Fe2 03 is an mixture of FeO and FeO2

In FeO ,Fe has +2 oxidation state

In FeO2,Fe has +4oxiation state

We know that ,

Eq wt=mol .wt/n Factor

In FeO

56/+2=28

In FeO2

56/4=14

Net eq wt=28+14/2=42/2=21
