Aqueous reaction with an insoluble product (precipitate)

$$\mathrm{AB}{\phantom{A}}_{\text{(aq)}}+\mathrm{CD}{\phantom{A}}_{\text{(aq)}}\to \mathrm{AD}{\phantom{A}}_{\text{(s)}}+\mathrm{CB}$$

Examples

C.M.E:

$$\mathrm{K}{\phantom{A}}_2\mathrm{CrO}{\phantom{A}}_{\text{4(aq)}}+\mathrm{Ba}(\mathrm{NO}{\phantom{A}}_3){\phantom{A}}_{\text{2(aq)}}\to \mathrm{BaCrO}{\phantom{A}}_{\text{4(s)}}+2\mathrm{KNO}{\phantom{A}}_{\text{3(aq)}}$$

C.I.E.:

$$2\mathrm{K}{\phantom{A}}_{\text{(aq)}}^{+}+\mathrm{CrO}{\phantom{A}}_4{\phantom{A}}^{2-}{\phantom{A}}_{\text{(aq)}}+\mathrm{Ba}{\phantom{A}}_{\text{(aq)}}^{2+}+2\mathrm{NO}{\phantom{A}}_3{\phantom{A}}^{-}{\phantom{A}}_{\text{(aq)}}\to \mathrm{BaCrO}{\phantom{A}}_4{\phantom{A}}_{\text{(s)}}+2\mathrm{K}{\phantom{A}}_{\text{(aq)}}^{+}+2\mathrm{NO}{\phantom{A}}_3{\phantom{A}}^{-}{\phantom{A}}_{\text{(aq)}}$$

N.I.E.:

$$\mathrm{CrO}{\phantom{A}}_4{\phantom{A}}^{2-}{\phantom{A}}_{\text{(aq)}}+\mathrm{Ba}{\phantom{A}}_{\text{(aq)}}^{2+}\to \mathrm{BaCrO}{\phantom{A}}_{\text{4(s)}}$$
