1. Why can the silver, mercury (I), and lead (II) ions be separated from all other cations in solution by the addition of hydrochloric acid? Indicate the reactions that occur.
Added by Megan H.
Step 1
Silver (Ag), mercury (I) (Hg2), and lead (II) (Pb) ions form insoluble chlorides when combined with chloride ions (Cl-). Most other cations form soluble chlorides. Therefore, when hydrochloric acid (HCl) is added to a solution containing these ions, the following Show more…

why can solid lead (ii) chloride be separated from solid silver chloride and solid mercury (i) chloride by the addition of hot water?

Many of the reactions utilized in this laboratory experiment involve substances with small solubility product constants. AgCl is one such substance. Nevertheless, a precipitate of AgCl will dissolve in either 6M HCl or 6M NH3. (1) Briefly explain why each of these reagents dissolves AgCl(s). Write appropriate equations to support your answer. (2) Briefly explain why it is possible to reprecipitate AgCl(s) by adding HCl to [Ag(NH3)2]+ ion but not by adding ammonia to [AgCl2]- ion. Write appropriate equations to support your answer.
