Consider the following reduction processes:

The reducing power of the metals increases in the order:

Canvas Classes · Accepted Answer

Strategy:
 Reducing power refers to the ability to oxidize yourself (act as a reducing agent). A species with a more negative standard reduction potential () is more easily oxidized and thus is a stronger reducing agent.

Rank by Reduction Potentials:
1. Ca:  (Most negative)
2. Mg: 
3. Zn: 
4. Ni:  (Least negative)

Order of Increasing Reducing Power:
Since more negative means more powerful:
Ni < Zn < Mg < Ca
