Qualitative analysis schemes are often based on selective precipitation of different cations. By carefully selecting reagents and conditions for reactions, groups of ions can be separated on the basis of their reactivity and the solubility of their salts.

Check your flowchart with your TA before beginning your analysis. To confirm your analysis of the unknown mixture, use the known solutions of single cations to observe positive confirmation tests. Record an observation for each cation's confirmation test in your notebook, either from your unknown or from a known solution.

Principles of the Qualitative Analysis of Cations The process of finding out what compounds are contained in a sample is called qualitative analysis. The process of finding out how much of a compound is contained in a sample is called quantitative analysis.

In this last section of our Qualitative Analysis experiment, we will again be dealing with only a fraction of the total number of ions that comprise Group III. If we were going to proceed to ... This tendency of our cations to form complex ions in certain kinds of solutions will once again be put to use in detecting iron,
