Pb(NO3)2 + 2 NaCl --> PbCl2 + 2 NaNO3. In this chemical equation, one molecule of lead(II) chloride and two molecules of sodium nitrate form when sodium chloride is added to an aqueous solution of lead nitrate.
Lead(II) chloride can be found in nature in the form of cotunnite, and it is a key lead-based reagent, with widespread industrial uses. It is used in the manufacture of infrared-transmitting and ornamental glasses. It can also be utilized as a colorant in paint. In laboratory conditions, lead(II) is formed by adding chlorine sources, such as hydrochloric acid, sodium chloride and potassium chloride, to aqueous solutions of lead(II) compounds, such as lead nitrate.
