A chemical reaction between two compounds in which parts of each are interchanged to form two new compounds (AB+CD=AD+CB) double decomposition, metathesis.

Example

The reaction between silver nitrate and sodium chloride is a double displacement reaction. The silver trades its nitrite ion for the sodium's chloride ion, causing the sodium to pick up the nitrate anion.

AgNo3 + Nacl ——> AgCl + NaNo3
