In the laboratory, students often learn to analyze mixtures of the common positive and negative ions, seperating and confirming the presence of the particular ions in the mixture. One of the first steps in such an analysis is to treat the mixture with hydrochloric acid, which precipatets and removes silver ion, lead (II) ion, and mercury (I) ion from the aqueous as the insoluble cho, ride slats. Write balanced net ionic equations for the precipitation reactions of these three cations with chloride ion.
