College Instructor edition with 36 experiments covering introductory and general chemistry topics.

Electrochemical Series

Lab Summary

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.

Theory

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.

Method

Students gain experience conducting the following procedures:

  • Constructing electrochemical cells.
  • Measuring the voltage produced in electrochemical cells with different metals and salt solutions as the anode and cathode.

Sensors / Equipment Used:

PASPORT Voltage-Current Sensor

(PS-2115)

Allows students to safely measure voltage and current simultaneously without overloading the sensor. For use with PASPORT Interfaces.
