Oxidation,Reduction and Redox Flashcards
1
Q
whats the oxidation state of an atom in its element state?
A
0 eg: 02
2
Q
What does it mean if the oxidation state has increased?
A
oxidised
3
Q
What does it mean if the oxidation state has decreased?
A
reduced
4
Q
What is an oxidising agent?
A
something that oxidises something else
but gets reduced itself
5
Q
What is a reducing agent?
A
something that reduces something else but gets oxidised itself
6
Q
What is a disproportionation reaction?
A
type of redox reaction where a single species is both oxidised and reduced
eg:
2H202 –> 2H20 + 02
oxygen is both reduced and oxidised
