Question

Differentiate between displacement and double displacement reactions.

Answer 1

Difference between displacement and double displacement reactions:

Displacement reaction	Double displacement reaction
i. Displacement reaction is a reaction in which one element displaces other element from its compound and takes its place therein.	Double displacement reaction is a reaction in which there is an exchange of ions between the reactants take place.
ii. For example: Fe + CuSO4 → FeSO4 + Cu	For example: When barium chloride solution is mixed with copper sulphate, the products formed: BaCl2 + CuSO4 → BaSO4 + NaCl
