Investigating Voltaic Cells

Figure from experiment 20 from Investigating Chemistry through Inquiry

Introduction

In electrochemistry, a voltaic cell is a specially prepared system in which an oxidation-reduction reaction occurs spontaneously. This spontaneous reaction produces an easily measured electrical potential. Voltaic cells have a variety of uses.

Objectives

In the Preliminary Activity, you will prepare a semi-microscale voltaic cell in a 24-well test plate. A voltaic cell is constructed by using two metal electrodes and solutions of their respective salts (the electrolyte component of the cell) with known molar concentrations. You will use a Voltage Probe to measure the potential of a voltaic cell with zinc and copper electrodes.

After completing the Preliminary Activity, you will first use reference sources to find out more about electrochemistry and voltaic cells before you choose and investigate a researchable question dealing with voltaic cells.
