Separation and Qualitative Analysis of Anions
Recommended for grades 9–12.
Introduction
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.
Objectives
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.
Sensors and Equipment
This experiment requires each of the following Vernier sensors and equipment (unless otherwise noted):
pH Sensor (optional)
Additional Requirements
You may also need an interface and software for data collection. What do I need for data collection?
Download Experiment Preview
The student-version preview includes:
- Step-by-step instructions for computer-based data collection
- List of materials and equipment
Note: The experiment preview of the computer edition does not include essential teacher information, safety tips, or sample data. Instructions for Logger Pro and other software (such as LabQuest App or TI handheld software, where available) are on the CD that accompanies the book. We strongly recommend that you purchase the book before performing experiments.
