The second part of your qualitative analysis experiment is the testing of anions. The process of analysis will be similar to Experiment 14A. Thus, if you did not complete 14A, it will be helpful to read the introductory comments and review the procedure.

The primary difference between cation analysis and anion analysis is in the separation steps; with cations, separation is common, but with anions, separation is rare.

As with Experiment 14A, you will first prepare a solution containing anions of your choice (the “known” solution), and then you will test an unknown solution to identify the anions it contains.


In this experiment, you will

  • Prepare and analyze a solution that contains six selected anions.
  • Analyze an unknown solution that contains a selection of anions.
