Based on the data, arrange the ions in increasing order of their reducing power :-Fe3+(aq) + e– → Fe2+(aq); E° = +0.77 VAl3+(aq) + 3e– → Al(s); E° = –1.66 VBr2(aq) + 2e– → 2Br–(aq); E° = +1.09 V(1) Br– < Fe2+ < Al(2) Fe2+ < Al < Br–(3) Al < Br– < Fe2+(4) Al < Fe2+ < Br–

Answer» Electrode potential data of few cells is given below. Based on the data, arrange the ions in increasing order of their reducing power :-
Fe3+(aq) + e– → Fe2+(aq); E° = +0.77 V
Al3+(aq) + 3e– → Al(s); E° = –1.66 V
Br2(aq) + 2e– → 2Br–(aq); E° = +1.09 V
(1) Br– < Fe2+ < Al
(2) Fe2+ < Al < Br–
(3) Al < Br– < Fe2+
(4) Al < Fe2+ < Br–
