Chemistry 112: Anion Analysis Page 7 ANION ANALYSIS M uch of the work you will be doing in the Chemistry 112 laboratory will be concerned with identifying positive and negative ions‚ that is‚ cations and anions‚ in solutions whose composition is unknown. This procedure is called QUALITATIVE ANALYSIS. The modern chemist frequently wishes to identify the constituents in a very small amount of substance‚ and so he depends heavily on instrumental methods of analysis. While the procedures

constituents as cations and non-metallic constituents as anions. In this experiment‚ you will analyze a known solution that contains the entire Group I cations—silver‚ lead‚ and mercury (I)—and an unknown solution to determine which ions are present and which are absent. II. DISCUSSION: The chlorides of Pb2+‚ Hg22+ and Ag+ are all insoluble in cold water. They can be removed as a group from solution by the addition of HCl. The reactions that occur are simple precipitations and can be represented by
