A When water is added to lead chloride, the solute sparingly dissolves with some undisclosed particles settling at the bottom of the beaker. Lead chloride is only sparingly soluble in water. When the dilute hydrochloric acid is added to the saturated solution of lead chloride, a white precipitate is formed. This is because of the common ion effect where the excess chloride ions from HCL cause lead chloride to precipitate. Pb2+ aq + 2Cl-aq PbCl2 s B 0.1M lead nitrate +0.1M sodium oxalate
