Featured in PASCO’s College Chemistry Instructor Guide
College Instructor edition with 36 experiments covering introductory and general chemistry topics.
Use a voltage-current sensor to construct an electrochemical cell that deposits copper onto another metal surface and to apply Faraday’s law to relate the total electric charge to the mass of metal deposited.
Students construct an electrochemical cell that deposits copper onto another metal surface. They also apply Faraday’s law to relate the total electric charge to the mass of metal deposited.
Students gain experience conducting the following procedures:
- Determining the change of mass of each electrode due to electroplating.
- Comparing the experimental changes in mass at each electrode to the expected change in mass due to the total electrical charge, calculated using Faraday’s law.
Sensors / Equipment Used:
Allows students to safely measure voltage and current simultaneously without overloading the sensor. For use with PASPORT Interfaces.
