Experiment 5 - Qualitative Analysis

Postlab Questions:

  1. Write the name, colour and formula for the precipitate formed in the confirmatory test for Pb2+, Hg22+ and Ag+ ions.
  2. Explain how you would separate PbCl2 (s) from a mixture of PbCl2 (s) and Hg2Cl2 (s). (Note: at the end of the separation you want pure PbCl2 (s) and Hg2Cl2 (s) in separate test tubes).
  3. Write the balanced chemical equations for the reactions which occurred when HCl (aq) was added to solutions of Pb(NO3)2, Hg2(NO3)2, and AgNO3 in Parts A, B, and C.
