Classic AP Requirement #14—Separation and Qualitative Analysis of Cations and Anions
Students analyze two solution sets of four cations and four anions. For each set, a specific qualitative scheme is followed to separately detect each of the four ions present. Students are then given two unknown solution sets to analyze. By following the qualitative schemes, students determine which cations and anions are present and which are absent from the two samples. Four to five 50-minute lab sessions will be needed to complete all four sets of analyses.
Complete for 24 students working in pairs.
