Making Cells in Chemistry

Added by Sam Holyman on Dec 15, 2008

This activity aims to teach students how to predict whether a cell will produce a high, low or no voltage. Experiments use electrodes and salt solutions to show that varying voltage levels can be produced. How this type of reaction is present in cells and batteries used in everyday life is also explained.

This item teaches:

  • about the convention for representing electrochemical cells
  • the factors that determine the voltage produced by an electrochemical cell
  • how cells are used to measure electrode potentials

Contents

Objectives

  • To understand that when two metals immersed in a salt solution are connected, a voltage is produced
  • To know that the further the metals are from each other on the Reactivity Series, the greater the voltage
  • To know that if the two samples of the same metal are immersed, no voltage is produced
  • To be able to predict whether a cell will produce a high, low or no voltage
  • To know that this type of reaction is present in cells and batteries used in everyday life
