Redox

Question 1

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

Oxidation

Answer 2

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

Question 3

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

Oxidising agent

Answer 4

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

Question 5

Redox reaction

Answer 5

A reaction in which both reduction and oxidation are occurring simultaneously

Question 6

Reducing agent

Answer 6

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

Question 7

Reduction

Answer 7

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