Dissolve lead oxide in dilute nitric acid to form lead nitrate. Then mix the resultant lead nitrate with sodium chloride to now form insoluble lead chloride and sodium nitrate. Filter the resultant solution and wash off the residue with distilled water. Dry the residue between filter papers, this is now lead chloride.
