5.6 Electrode Potentials

Question 1

E.M.F.

Answer 1

The potential difference measured when two half cells are connected.

Question 1

Standard Electrode Potential

Answer 1

The potential difference measured when a half-cell is connected to the standard hydrogen electrode under standard conditions.

Question 2

Oxidation (Inorganic)

Answer 2

The loss of electrons from a substance or an increase in oxidation state (oxidation number).

Question 3

Reduction (Inorganic)

Answer 3

The gain of electrons by a substance or an decrease in oxidation state (oxidation number).

Question 4

Redox

Answer 4

This is a reaction where both oxidation and reduction occur.

Question 5

Disproportionation

Answer 5

This is redox where oxidation and reduction both occur to a element of the same species.
