1.7 Oxidation, Reduction and Redox Equations Definitions

Question 1

Define Half equation

Answer 1

A full redox equation can be split into two half-equations, one involving oxidation and the other involving reduction. This concept is useful for balancing complex redox reactions.

Question 2

Define Oxidation

Answer 2

Process involving the loss of electrons. Results in an increase in oxidation number.

Question 3

Define Oxidation state

Answer 3

The charge of an ion or a theoretical charge of an atom in a covalently bonded compound assuming the bond becomes ionic.

Question 4

Define Redox reaction

Answer 4

A reaction in which both reduction and oxidation are occurring simultaneously.

Question 5

Define Oxidising agent

Answer 5

Electron acceptors. The elements/compounds which accept electrons causing itself to be reduced

Question 6

Define Reducing agent

Answer 6

Electron donors. The elements/compounds which donate electrons causing itself to be oxidised

Question 7

Define Reduction

Answer 7

Process involving the gain of electrons. Results in a decrease in oxidation number.
