A reaction in which a substance loses electrons is called:
The oxidation number of an element in its free state is:
In a disproportionation reaction:
The total number of electrons lost by oxidation must equal the total number of electrons gained by reduction. This principle is the basis of:
An oxidizing agent is a substance that:
The electrode where oxidation occurs is called the:
The standard hydrogen electrode (SHE) is assigned a potential of:
The standard cell potential is calculated using the formula:
In the electrochemical series, elements with the most negative reduction potentials are the:
