Balance the following oxidation-reduction reaction using the oxidation number method: Fe + Br₂

\to

Fe³⁺ + Br^-
In the balanced equation,the coefficient of Br^- is

Quizplus · Accepted Answer

In the balanced equation, the oxidation of Fe to Fe^3+ involves a change of +3 in oxidation state, and the reduction of Br2 to Br^- involves a change of -1 per bromine atom. Therefore, 6 electrons are needed to balance the equation, requiring 6 Br^- ions.
