Featured in PASCO’s College Chemistry Instructor Guide
College Instructor edition with 36 experiments covering introductory and general chemistry topics.
Use a voltage sensor to determine the half-reactions that relate to the anode and cathode of a galvanic cell and to calculate the electromotive force for a battery.
Students determine the half-reactions that relate to the anode and cathode of a galvanic cell. They also calculate the electromotive force for a battery, knowing the electrode materials used, by comparing the reduction potentials of metals.
Students gain experience conducting the following procedures:
Beaker, 50-mL - 6
Glass plate (5 × 5 in)
Disposable droppers, 1 mL - 6
Iron strip, 1-cm × 1-cm
Lead strip, 1-cm × 1-cm
Copper strip, 1-cm × 1-cm
Silver wire, 1-cm
Zinc strip, 1-cm × 1-cm
Circular filter paper, 11-cm diameter
1.0 M Zinc sulfate (ZnSO4) - 10 mL
1.0 M Iron sulfate (FeSO4) - 10 mL
1.0 M Copper sulfate (CuSO4) - 10 mL
1.0 M Silver nitrate (AgNO3) - 10 mL
1.0 M Lead nitrate (Pb(NO3)2) - 10 mL
1.0 M Sodium nitrate (NaNO3) - 20 mL
This experiment may require software and an interface for data collection.
