Question

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. Y > X > Z
• B. Z > X > Y
• C. X > Y >Z
• D. Y >Z >X

Answer 1

Answer: (B)

Z > X > Y

Answer 2

$Z > X > Y$; higher the reduction potential lesser the reducing power
