Question

Choose the correct answer from the options given below.

The formula of iron (III) sulphate is ______.

Options

•  Fe₃SO₄ 

•  Fe(SO₄)₃

• Fe₂(SO₄)₃

• FeSO₄ 

Answer 1

The formula of iron (III) sulphate is Fe₂(SO₄)₃.

Explanation:

\[\ce{Fe^{3+} SO^{2-}_4}\]

\[\ce{F\overset{3}{e} ⤩ S\overset{3}{O4} => F\underset{2}{e} ⤩ S\underset{3}{O4}}\]

∴ Fe₂(SO₄)₃
