Redox Reactions Flashcards
What is a thermite mixture
Aluminium and iron(III) Oxide
Aluminium + iron(III) Oxide =
Aluminium Oxide + Iron
Define a redox reaction
Where reduction and Oxidation happen at the same time
What happens to Iron(III) Oxide
It loses oxygen and is reduced to iron
What happens to aluminium
Aluminium gains oxygen and is oxidised to aluminium oxide
What is an oxidising agent
An substance that can remove electrons from other substances- oxidising them
What is a reducing agent
A substance that can give electrons to other substances- Reducing them
Reactivity series of metals
1) Magnesium
2) Zinc
3) Iron
4) Tin
5) Copper
Zinc + copper Sulfate =
Zinc Sulfate + copper
What happens when a strip of zinc dipped into
Copper (II) Sulfate solution
What happens when a strip of zinc foil is dipped into copper (II) solution
It becomes coated I copper and the blue solution gradually fades
What happens to the temperature in an exothermic reaction
It rises
What can a more reactive metal do
Displace a less reactive metal
