Question

What is the appropriate chemical formula for Iron(III) Sulfate? Sulfate is SO_4^2 Fe3SO4 O a . Fe2(SO4)3 O b. O c. Fe2SO4 O d. Fe2(SO4)2 O e. Fe3(SO4)2

Answer 1

Answer: The chemical formula of Iron (III) sulfate is
`Fe_2(SO_4)_3`

Step-by-step explanation:

Iron is the 26th element of periodic table having electronic configuration of
`[Ar]3d^64s^2`.

To form
`Fe^(3+)` ion, this element will loose 3 electrons.

Sulfate ion is a polyatomic ion having chemical formula of
`SO_4^(2-)`

By criss-cross method, the oxidation state of the ions gets exchanged and they form the subscripts of the other ions. This results in the formation of a neutral compound.

So, the chemical formula for Iron (III) sulfate is
`Fe_2(SO_4)_3`
