(N/A) Displacement reactionsDouble displacement reactions$1.$ In these reactions, a more active element displaces a less active element from its salt solution.$1.$ In these reactions, there is an exchange of ions between two reactants.$2.$ These reactions are usually slow and take longer time for their completion.$2.$ These reactions are usually fast and take place instantaneously.$3.$ During these reactions, a change of color usually takes place. Example: $Fe(s) + CuSO_4(aq) 	o FeSO_4(aq) + Cu(s)$ (Blue to Light green).$3.$ During these reactions, precipitates are usually formed. Example: $AgNO_3(aq) + NaCl(aq) 	o AgCl(s) \downarrow + NaNO_3(aq)$ (White precipitate).
