Question

Which charge does iron (Fe) have in iron sulfate (FeSO4)?A) +2B) -1C) -2D)+1

Answer 1

+2. Option A is correct.

Explanations:

Given the compound FeSO₄, we are to get the charge on Iron(Fe). From the given compound;

• The o,xidation state ,of sulfur (S) is +6

,

• Oxidation state of oxygen is -2(4) = -8

Let the oxidation state of iron (Fe) be "x"

Taking the sum of the oxidation state and equate to zero to get the value of "x"

`x+6+(-8)=0`

Simplify the result

`\begin{gathered} x+6-8=0 \\ x-2=0 \\ x-2+2=0+2 \\ x=+2 \end{gathered}`

This shows that the charge on iron in FeSO4 is +2
