Description
Lead halide precipitates. Lead (II) nitrate (Pb(NO3)2) was added to three test tubes containing, left to right potassium chloride (KCl), potassium bromide (KBr) and potassium iodide (KI). Respective lead (II) halides were formed as precipitates. The reactions are KX + Pb(NO3)2 -> PbX2 + KNO3, where X = Cl, Br, or I. All solutions were 0.5M concentration. These double displacement reactions can be used as a test for presence of halogens in a solution.
