Question

Calculate the oxidation number of sulphur in \\(FeSO_{4}.7H_{2}O\\)?

Answer 1

Answer:

6

Explanation:

We are given that an hydrous salt

$FeSO_4\cdot &H_2O$

We have to find the oxidation number of sulfur in given salt.

Suppose , oxidation number of sulfur=x

Oxidation number of water=0

Oxidation number of Fe=+2

Therefore, $2+x+4(-2)=0$

$2+x-8=0$

$x-6=0$

$x=6$

Hence, oxidation number of sulfur=6
