Reduce all coefficients to the lowest possible integral values.
Include H2O(l) and H+(aq) appropriately to complete the equation.

Fe(s) + Cl−(aq) ® HFeCl4(aq) + H2(g)

My answer :  Fe(s) + 4Cl^- + 3H^+(aq) -> HFeCl4(aq) + H2(g)

what am I doing wrong?

Fe has two oxidation levels. The highest one cannot be achieved in the presence of a strong reductor (ie hydrogen)
