Pembahasan

Daya reduksi unsur halogen meningkat dari atas kebawah open parentheses I to the power of minus sign greater than Br to the power of minus sign greater than Cl to the power of minus sign greater than F to the power of minus sign close parentheses. Ion I to the power of minus sign memiliki daya reduksi yang paling besar serta memiliki potensial sel standar yang lebih rendah dari ion Fe to the power of 3 plus sign sehingga dapat mereduksi ion Fe to the power of 3 plus sign.
