Oxidation, reduction and redox Flashcards
1
Q
Why is it called a redox reaction?
A
Its called a redox reaction because oxidation and reduction happen simultaneously in the reaction.
2
Q
What is oxidation number?
A
Oxidation number is the oxidation state.
3
Q
What are oxidising agents?
A
Oxidising agents accepts electrons from the electrons from the species that are being oxidised. Therefore it gains electrons and is reduced. This is seen as a reduction in oxidation number ( gets more negative ).
4
Q
What is a reducing agent?
A
A reducing agent donates electrons to the species being reduced. Therefore loses electrons and is oxidised . This is seen as a increase in oxidation ( gets more positive ).
5
Q
What do half equations show?
A
They show the seperate oxidation and reduction reactions.
