Then product forms at the cathode is Fe metal
Fei3 undergo dissociate to form fe^ 3+ + 3I^-
Fe^3+ move to the negative electrode(cathode) where they are reduced to metallic iron by gaining 3e-
that is Fe^3+(aq) + 3e- = Fe(s)
Dobereiner could find only three triads; . i.e total of 9 elements only. However the total number of elements were more than that of those encompassed in Dobereiner's Triad. Thus, Dobereiner's could not be classify most of the elements known at that time
