Question

Oxidation state of Fe in Mohr's salt..

Answer 1

The formula of the Mohr salt is written as follows:

FeSO4 (NH4)2SO4.6H2O

 The total molar mass of the substance is calculated as follows:

You should add up the molecular mass of the elements contained in the compounds.

The total weight is about 392 g per mol.

Looking at the formula one can say that Oxidation number of NH4 ion is +1

The oxidation number of SO4 ion is -2

Oxidation number of hydrogen ion is +1

Oxidation number of oxygen is

-2 X + 2(+1) + 2(-2) + 6[2(1) - 2]

= 0 X + 2 - 4 + 6[2 - 2]

= 0 X - 2 + 6(0)

= 0 X - 2 + 0 = 0 X - 2

= 0 X = 2

 Hence oxidation number of Fe is +2

Therefore the new name is Ammonium iron (II) tetraoxosulphate (VI) hexahydrate salt

Answer 2
