Lesson 1.2.4

Lesson 4 - Using Voltaic Cells

Get Focused

We use voltaic cells to operate a wide variety of portable electronic devices. In this lesson we will investigate the fundamental chemical principles behind the operation of voltaic cells and understand their operation.

Consider the following essential questions as you complete Lesson 4:

  • What is a spontaneous reaction?
  • What is a galvanic cell ?
  • How do you determine whether a redox reaction will be spontaneous or not ?
  • What happens at the anode and cathode in a voltaic cell
