Strength of reducing agent
For one of the homework problems, it asks to rank metals of increasing strength of reducing agent. How would we go about answering these type of questions?

Re: Strength of reducing agent
The smallest (more negative) Reduction potential is a stronger reducing agent

Why is that?

Re: Strength of reducing agent
If something is more negative, then it has more reducing power. To have more reducing power means it can gain more electrons. When E cell is more negative, this means that the reducing power is very high and and it can be easily oxidized.

Re: Strength of reducing agent
The more negative a reduction potential is, the stronger the reducing agent. The less negative/more positive a reduction potential is, the stronger the oxidizing agent.

Re: Strength of reducing agent
The more positive a reduction potential is the easier it is for it to be reduced, and vice versa for an element to be oxidized. Therefore a lower reduction potential would make the best reducing agent.

Re: Strength of reducing agent
The more negative the E, the more strong it is as a reducing agent (the thing being oxidized). Another way of saying it is a good donator.

Re: Strength of reducing agent
Also, remember that the reducing agent is associated with the oxidation reaction.

Re: Strength of reducing agent
The more negative the value of Ecell is the stronger the reducing agent is.

Re: Strength of reducing agent
Reducing agents are most spontaneous when in oxidation half reactions and therefore they want to lose e-. In order to rank, we can compare the E⁰. The most negative value should be the strongest reducing agent.
