Problem: Find and report the reduction potentials of lithium, sodium, and potassium.Which is the best reducing agent?Which is the worst reducing agent?

FREE Expert Solution

The strongest reducing agent would be the element that would be easily oxidized or easily loses an electron:

• it will be the species moving away from the electrons

• it will be the anode which means it will have the smallest Ecell


The ease to remove an electron from an element is also related to cell potential.

• Smaller (↓) E° → oxidation → stronger reducing agent

• Larger (↑) E° → reduction → weaker reducing agent

We shall refer to the reduction potential table below:
