Module 3—Electrochemical Reactions

Lesson Summary

 

In Lesson 1 you considered the following question:

• What is an electrochemical change?

By observing the reaction between zinc and aqueous silver ions you were able to see evidence of a chemical reaction that can be explained by an electron transfer between reactants. You also learned how to write, balance, and interpret half-reactions that describe reduction or oxidation processes.

 

In the next lesson you will investigate electrochemical changes involving other metals, and you will conduct an experiment to investigate the difference in the reactivity of selected metals.
