Displacement Reactions
Reactivity Series
A displacement reaction is a reaction where a more reactive metal takes the place of a less reactive one. For Example:
Zinc Sulphate + Calcium > Calcium Sulphate + Zinc
Copper Chloride + Iron > Iron Chloride + Copper
Lead Nitrate + Aluminum > Aluminum Nitrate + Lead
Use the reactivity series to determine whether a metal is more or less reactive than another.
