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.
