Conductivity of Solutions

Published on 12/05/2010

Activity Overview

This is an investigation of conductivity and concentration of ionic solutions. Students create a plot of conductivity and concentration and calculate a mathematical model for this relationship. They will also look at substances that release differing numbers of ions.

Objectives

  • Describe the effects of ion concentration on solution conductivity.

 

About the Lesson

The following questions will guide student exploration during this activity:

  • How is the concentration of ions in a solution related to the conductivity of the solution?
  • How does the identity of an ionic compound affect the relationship between concentration and conductivity?
