Answer: The chemical formula of Iron (III) sulfate is [tex]Fe_2(SO_4)_3[/tex]
Explanation:
Iron is the 26th element of periodic table having electronic configuration of [tex][Ar]3d^64s^2[/tex].
To form [tex]Fe^{3+}[/tex] ion, this element will loose 3 electrons.
Sulfate ion is a polyatomic ion having chemical formula of [tex]SO_4^{2-}[/tex]
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 [tex]Fe_2(SO_4)_3[/tex]
