Question

Standard reduction potential for Al3+/Al, Fe2+/Fe, Br/Br- are -1.66 V, -0.45 V, 0.19 V. Order of their reducing capacity is (A) Al > Fe > Br (B) Br > Fe > Al (C) Al > Br > Fe (D) Fe > Al > Br

Tardigrade Admin · Accepted Answer

Metals having high negative values of standard reduction potentials have the tendency to lose electrons readily. The non-metals having high positive values of standard reduction potentials have the tendency to accept electrons readily.

∴

Order of reducing character would be

A l > F e B r

Q. Standard reduction potential for $A l^{3 +} / A l$ , $F e^{2 +} / F e$ , $B r / B r^{-}$ are $- 1.66 V$ , $- 0.45 V$ , $0.19 V$ . Order of their reducing capacity is

$A l > F e > B r$

$B r > F e > A l$

$A l > B r > F e$

$F e > A l > B r$

Metals having high negative values of standard reduction potentials have the tendency to lose electrons readily. The non-metals having high positive values of standard reduction potentials have the tendency to accept electrons readily.
$∴$ Order of reducing character would be
$A l > F e B r$
