Question
Standard electrode potential of three metal X, Y and Z are -1.2 V, +0.5 V and -3.0 V respectively. The reducing power of these metals will be
-
Y > X > Z
-
Z> X> Y
-
X > Y > Z
-
Y > Z > X
Solution
B.
Z> X> Y
Exo = -1.2 V;
Eoy = + 0.5 V;
Eoz = -3.0 V;
therefore, Z > X > Y
Because, higher the reduction potential, lesser the reducing power.
therefore, Z > X > Y
Because, higher the reduction potential, lesser the reducing power.
