Study Notes
Displacement Reactions
- Iron displaces copper from copper sulphate solution, a process known as a single displacement reaction.
- The brownish color of the iron nail after the reaction with copper sulphate solution is due to the formation of copper oxide.
Displacement Reaction with Zinc
- In the reaction between zinc and copper sulphate, copper is being displaced from its compound.
Precipitation Reaction
- When sodium sulphate solution is mixed with barium chloride solution, a white precipitate of barium sulphate is formed.
- A reaction that results in the formation of an insoluble solid, such as the formation of barium sulphate, can be called a precipitation reaction.
Double Displacement Reaction
- In the double displacement reaction between lead and copper chloride, copper is displaced from its compound.
