Using Standard Potentials: Cell EMF

Oxidizing and Reducing Agents

• The more positive E_red the stronger the oxidizing agent on the left.

• The more negative E_red the stronger the reducing agent on the right.

• A species on the higher to the left of the table of standard reduction potentials will spontaneously oxidize a species that is lower to the right in the table.

• That is, F2 will oxidize H2 or Li; Ni2+ will oxidize Al(s).

• Any species on the right will spontaneously reduce anything that is higher to the left in the series.
