Purpose: The purpose of this lab was to analyze unknown solutions to see if it contained the ions Ag, Pb, Hg.Procedure: For each unknown solution we added 5 drops of cold 6M HCL. Mixed and centrifuged. We tested for complete precipitation by adding an additional drop of 6M HCL. We discarded the dct. and saved the ppt. We washed the ppt twice with 1 ml portions of cold .1M HCL. Discarded the washings both times. Saved the ppt. To the ppt. we added 1 ml of hot water, and placed tube in hot wat
