Lesson 5

Module 4—Batteries and Balance

Lesson Summary

 

In Lesson 5 you considered the following question:

  • What are the important quantitative relationships within operating electric and electrolytic cells?

This lesson extended your application of the stoichiometric method to include amperage and time. You used the stoichiometric method to determine the chemical quantity of electrons participating in a reaction. Since electrons determine the chemical changes in these cells, they can be treated as the limiting reactant in many electrochemical systems. As such, electrons can be used to calculate the quantities of products or reactants in the system that participates in the process.
