Definition

• a chemical reaction where a more reactive element replaces a less reactive element in a compound

• Example Of Displacement reaction would be iron and copper sulfate, iron and copper have a reaction and bond together, here this a displacement reaction as iron is a reactive element and copper sulfate is less reactive

Double Displacement Reaction

• A double displacement reaction is a type of chemical reaction where two compounds exchange ions to form two new compounds

• Example -: HCI + NaOH = NaCI + H20, this is a example were compounds exchange ions to form 2 new compounds

Metals

• Metals are extracted by the process of displacement reaction as the more reactive replaces the least reactive one

• extracting iron from its ore using carbon or aluminum, or extracting copper from copper sulfate solution using iron or zinc

Purpose Of Displacement Reaction

• Extract Metals:

  • Example: Iron + Copper sulfate → Iron sulfate + Copper This helps extract copper metal from its compound.

• Reactivity Comparison:

  • Used to test which metal is more reactive (based on the reactivity series).

• Form New Compounds:

  • Used in labs or industries to form new chemicals for desired reactions.

• Purify Substances:

  • Used in metallurgy and chemistry to isolate pure elements.
