Question

What are the differences between displacement and double displacement reactions ?

Answer 1

Displacement reaction

1) In these reaction ,more reactive metal displace less reactive metal from its compound
2) it is a slow reaction
3) change of colour take place
4) e.g (fe2+)+cuso4
---->feso4+(cu2+)

Double displacement reaction

1) there is an exchange of ions between two reactant
2) it is a fast reaction
3) precipitate are formed
4) e.g (agno3+)+nacl
-->(agcl+)+nano3
