WebExpert Answer. Lab 5 Qualitative Analysis of Ions Objectives: 1. To learn how ions can be separated and identified by making use of their specific chemical properties. 2. To learn what a precipitate is, how to recognize if one has formed, and how to separate the precipitate from the solution using filtration. 3. WebSep 22, 2024 · Your objective will be to identify which Group III cation (s) are present in your unknown sample. Remember that in qualitative analysis the ions in a given group are first separated from each other, and then a characteristic test is performed for each ion in order to confirm the presence of that ion.
