double-displacement reaction

Explanation:

We have the chemical reaction:

Na₂S (aq) + Cd(NO₃)₂ (aq) → CdS (s) + 2 NaNO₃ (aq)

where:

(aq) - aqueous

(s) - solid

This is a double-displacement reaction because the reactants exchange atoms or group of atoms between themselves to form the products. To drive the reaction to the right, one of the products is a precipitate.

Generally we can express the double-displacement reaction as following:

AB + CD → AC + BD
