| Displacement reaction | Double displacement reaction |
| In a displacement reaction, a more reactive element replaces a less reactive element from a compound. | In a double displacement reaction, two atoms or a group of atoms switch places form new compounds. |
| In a displacement reaction, one displacement takes place.
A + BX → AX + B |
In a double displacement reaction, two displacements take place to complete the reaction.
AB + CD → AC + BD |
| Change in colour takes place with no precipitate forms. | Precipitate is formed. |
| Metals react with the salt solution of another metal. | Salt solutions of two different metals react with each other. |
| Examples:
2KI + Cl2 → 2KCl + I2 is a displacement reaction. CuSO4 + Zn → ZnSO4 + Cu is also a displacement reaction. |
Examples:
Na2SO4 + BaCl2 → BaSO4 + 2NaCl is a double displacement reaction. 2KBr + BaCl2 → 2KCl + BaBr2 is also a double displacement reaction. |
