Chemistry through Inquiry Teacher Guide

(PS-2871C)

Features over 25 inquiry based labs covering the fundamental concepts of lab skills, structure & properties of matter, chemical reactions and more.

Electrochemical Battery

Lab Summary

Use a voltage sensor to place metal reactants in their proper order on the table of standard electrode potentials.

Theory

Experimentally place metal reactants in their proper order on the table of standard electrode potentials. Through this investigation, students:

  • Describe electricity as the flow of electrons.
  • Learn that some metals form ions easier than others, and that the ease with which ions are formed determines the amount of energy they can produce.
  • Learn that electrochemical batteries (voltaic cells, batteries) produce useable energy by separating two halves of a spontaneous chemical reaction in which the products have lower potential energy than the reactants.
  • Learn that an electrochemical battery contains two different metals, a path for ion movement,and an electrolyte solution.

Method

Students conduct the following procedures:

  • Construct electrochemical batteries using electrolyte solutions, wires, and various metal electrodes.
  • Measure voltage produced in an electrochemical battery using different metals as the anode and copper as the cathode.
