A Student-Constructed Galvanic Cell for the Measurement of Cell Potentials at Different Temperatures
Jakubowska, Anna
Journal of Chemical Education, v93 n5 p915-919 May 2016
A student-made galvanic cell is proposed for temperature measurements of cell potential. This cell can be easily constructed by students, the materials needed are readily available and nontoxic, and the solution applied is in an attractive color. For this cell, the potential values are excellently reproducible at each temperature, and the potential-temperature coefficient is well measurable. This experiment illustrates the determination of thermodynamic properties of a cell reaction, such as changes in entropy, enthalpy, and Gibbs energy through measurements of cell potential as a function of temperature. Students are led to understand the significance of those quantities. They also get to know the role of a supporting electrolyte in the electrochemical system.
