Featured in PASCO’s College Chemistry Instructor Guide
College Instructor edition with 36 experiments covering introductory and general chemistry topics.
Analysis of Cations
Use chemical reactions and chemical properties to identify the cations present in a mixture by systematically reacting the unknown with various reagents.
Students use chemical properties to qualitatively classify and identify the cations present in a solution.
Students gain experience conducting the following procedures:
- Organizing and tracking the results of multiple reactions.
- Performing basic laboratory separation processes.
