Experiment 5 - Qualitative Analysis
- Write the name, colour and formula for the precipitate
formed in the confirmatory test for Pb2+, Hg22+
and Ag+ ions.
- 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).
- 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.
