Redox Reactions Flashcards
1
Q
What is a redox reaction
A
is a reaction that involves both reduction and oxidation
2
Q
What is oxidation in terms of electrons
A
is the loss of electrons
3
Q
What is reduction in terms of electrons
A
is the gain of electrons
4
Q
What is the oxidising agent
A
is a species that oxidies another speicies by removing one or more electrons
When an oxidising agent reacts it gains electrons and is therefore reduced
5
Q
What is the reducing agent
A
a species that reduces another species by adding one/more elctrons
When a reducing agent react it loses electrons and is thefore oxidised
6
Q
Write a half equation for the oxidiation of Mg into Mg2+
A
Mg -> Mg2+ + 2e-
7
Q

A
O2+ 4e- -> 2O2-
