9. Redox Processes

Question 1

What is a redox reaction?

Answer 1

The simultaneous reduction and oxidation.

Question 2

What is an oxidation number?

Answer 2

A theoretical description of the charge that an atom would have if it were to be bonded ionically.

Question 3

What does an increase in oxidation number mean?

Answer 3

Oxidation has occurred.

Question 4

List the 8 rules of oxidation numbers.

Answer 4

1. Uncombined elements have an O.N of 0.
2. The O.N on a monatomic ion= the charge on an ion.
3. Group 1= +1
4. Group 2= +2
5. Fluorine= -1
6. Hydrogen= +1
7. Oxygen= -2
8. Sum of O.N= total charge on the compound.
