Le Châteliers Principle when a stress is applied to a system the
more solid PbCl2 will dissolve and the the solubility of the PbCl2(s) can be decreased ... PbCl2 has Ksp = 1.2 x 10-5 so Ksp of precipitate must.
Group I Precipitation of Insoluble Chlorides
Thus PbCl2 can be separated from the other two chlorides by adding hot water. In hot water

Carcinogen: ACGIH A3: Animal carcinogen: Agent is carcinogenic in experimental animals at a relatively high dose, by routes of administration, at sites, of histologic types, or by mechanisms not considered relevant to worker exposure. Available epidemiologic studies do not confirm an increased risk of cancer in exposed humans. Available evidence suggests that the agent is not likely to cause cancer in humans except under uncommon or unlikely routes or level of exposure. NTP-R: Reasonably anticipated to be a carcinogen, limited evidence of carcinogenicity from epidemiologic studies. EPA-B2: Probable human carcinogen, sufficient evidence from animal studies; inadequate evidence or no data from epidemiologic studies.
