Redox

Question 1

What is a redox reaction

Answer 1

A redox reaction is a reaction that involves both reduction and oxidation

Question 2

What is an oxoanion

Answer 2

An oxoanion ion is an ion the general formula of XxOy z- ( where X represents any element while O represent an oxygen atom)

Question 3

What is a half equation

Answer 3

A half equation is an ionic equation used to describe either the gain, or the loss of electron during a redox reaction

Question 4

What is a displacement reaction

Answer 4

Displacement reaction are redox reaction which can be used to compare the relative strength of metal as reducing agents and non-metal as oxidising agent

Question 5

What is a spectator ion

Answer 5

Spectator ion are ions which are present in solution but takes no part in a reaction

Question 6

What is oxidation

Answer 6

Oxidation is a change which make the oxidation number of an element more positive or less negative

Question 7

What is reduction

Answer 7

Reduction is a change which make the oxidation number of an element more negative or less positive

Question 8

What is an ionic equation

Answer 8

Ionic equation describe chemical change by showing only the reacting ions and any other reacting atoms or molecules while leaving out spectator ions

Question 9

What is oxidation state

Answer 9

Oxidation state are the stats of oxidation, or reduction, show by an element in its chemistry
