A precipitation reaction is a reaction in which soluble ions in separate solutions are mixed together to form an insoluble compound that settles out of solution as a solid. That insoluble compound is called a precipitate.

Example : When lead nitrate is treated with sulphuric acid , a white precipitate of lead sulphate is formed.

Pb(NO3)2 + H2SO4     →   PbSO4  + 2HNO3
