1
Q
Disproportionation
A
A reaction in which a substance is simultaneously reduced and oxidised.
2
Q
Oxidation
A
The loss of electron(s) which leads to an increase in oxidation number
3
Q
Oxidation number
A
The charge of an ion or a theoretical charge of an atom in a covalently bonded compound assuming the bond becomes ionic.
4
Q
Oxidising agent [2]
A
-A species which brings about oxidation by gaining electrons.
-The oxidising agent is itself reduced.
5
Q
Redox reaction
A
A reaction in which both reduction and oxidation are occurring simultaneously.
6
Q
Reducing agent [2]
A
-A species which brings about reduction by losing electrons.
-The reducing agent is itself oxidised.
7
Q
Reduction
A
The gain of electron(s) which leads to a decrease in oxidation number
