Can someone explain why there is OH in the Standard Reduction Potentials Table

Final answer:

The OH in the Standard Reduction Potentials Table refers to the hydroxide ion. To balance a redox reaction, you need both a reduction half-reaction and an oxidation half-reaction. The reduction potential is measured against the standard hydrogen electrode (SHE) and is used to determine the driving force of the reaction.

Step-by-step explanation:

The OH in the Standard Reduction Potentials Table refers to the hydroxide ion. The table lists reduction reactions, but in order to balance a redox reaction, you need both a reduction half-reaction and an oxidation half-reaction.

To create the oxidation reaction, you simply reverse the reduction reaction and change the sign of the E1/2 value. The reduction potential is measured against the standard hydrogen electrode (SHE) and is used to determine the driving force of the reaction.
