CHEMISTRY - displacement reactions and extracting metals

Displacement Reactions
-
1 of 7
Displacement of Metals Rule
"a more reactive metal will displace a less reactive metal from the aqueous solution of one of its salts"
2 of 7
Oxidisation
the loss of electrons - to have oxygen added
3 of 7
Reduction
the gain of electrons - the loss of oxygen
4 of 7
Thermal Deocmposition
used for elements below copper in the reactivity series - the compound is heated and it decomposes to form the metal
5 of 7
Displacement with Carbon
used for elements below carbon in the reactivity series - the compound is heated with carbon, and the carbon displaces the less reactive metal
6 of 7
Electrolysis
used for elements above carbon in the reactivity series - an electrical current is passed through the moltern compound
