Q. Standard electrode potential of three metals X, Y and Z are –1.2 V, +0.5 V and –3.0 V respectively. The reducing power of these metals will be
A) X > Y > Z
B) Y > Z > X
C) Y > X > Z
D) Z > X > Y
Explanation
[Solution from source] The more negative the standard reduction potential, the more readily the metal is oxidised, so the stronger the reducing agent. Order: Z (−3.0 V) > X (−1.2 V) > Y (+0.5 V). Answer (4).
