Featured in PASCO’s College Chemistry Instructor Guide
College Instructor edition with 36 experiments covering introductory and general chemistry topics.
Use chemical reactions and chemical properties to analyze solutions of known anions, using the results to analyze a solution of unknown anions.
Students analyze solutions of known anions and apply the knowledge gained to identify the anions in an unknown solution.
Students gain experience conducting the following procedures:
Test tube, 10-mL - 13
Test tube rack
Pipets, 1 mL, disposable - 13
Stirring rods - 5
Litmus paper - 15
0.2 M Sodium sulfate (Na2SO4) -10 mL
0.2 M Monopotassium phosphate (KH2PO4) - 5 mL
0.2 M Sodium nitrate (NaNO3) -5 mL
0.2 M Sodium chloride (NaCl) - 5 mL
Unknown anion solution (use Na2SO4, KH2PO4, NaNO3, NaCl) - 20 mL
0.2 M Barium nitrate (Ba(NO3)2) - 5 mL
Saturated iron(II) sulfate (FeSO4) - 2 mL
0.1 M Silver nitrate (AgNO3) - 5 mL
6 M Nitric acid (HNO3) - 5 mL
5 M Ammonia (NH3) - 5 mL
3 M Sulfuric acid (H2SO4) - 5 mL
Concentrated H2SO4 - 2 mL
Distilled water - 10 mL
This experiment may require software and an interface for data collection.
