Answer
| Neutralization reaction | Precipitation reaction |
|---|---|
| A reaction between two compounds - base and acid to give two new compounds - salt and water - by interchange of radicals is called a Neutralization reaction. | A reaction between two compounds in aqueous solution state to give two new compounds one of which is insoluble (precipitate) is called a Precipitation reaction. |
| For example: NaOH + HCl ⟶ NaCl + H2O | For example: Pb(NO3)2 + 2NaCl ⟶ 2NaNO3 + PbCl2 |
