Key Stage 4
Meaning
A precipitate is a solid insoluble compound formed by the chemical reaction between two other chemicals in solution.
About Precipitates
- The reactants in a precipitation reaction are aqueous or gaseous but at least one of the products is an insoluble solid.
- Some common precipitate reactions you may know are:
- Lead Nitrate + Potassium Iodide → Potassium Nitrate + Lead Iodide
\(Pb(NO_3)_2(aq) + 2KI(aq) → 2KNO_3(aq) + PbI_2(s)\)
\(CaO(aq) + CO_2(g) → CaCO_3(s)\)
