Question 3 • Chemistry
As written, the equation is unbalanced: it has two iodine atoms on the left but only two on the right, and the charges also do not match. In acidic solution, the half-reaction method adds H⁺ and H₂O to balance the redox reaction, giving 5 I⁻ + IO₃⁻ + 6 H⁺ → 3 I₂ + 3 H₂O. So the true statement is that the equation is unbalanced but can be balanced by the half-reaction method.
