Consider the following reduction processes
Zn 2+ + 2e - 
Zn (s); E° = -0.76 V
Ca 2+ + 2e 
Ca (s); E° = -2. 87 V
Mg 2+ + 2e - 
Mg (s); E° = -2.36 V
Ni 2+ + 2e - 
Ni (s); E° = -0.25 V
The reduction power of the metals increases in the order
Text Solution
Verified by ExpertsThe correct answer is:
B
Reducing power oc Tendency to undergo oxidation
So, reducing power decreases as Ca > Mg > Zn > Ni
