Oxidation-Reduction

=Oxidation and Reduction= electrons.
 * Oxidation-reduction reactions** or **redox reactions** involve the transfer of

Part I - READ

 * If you have ever left your skates or other metal toys out in the rain, then you are probably familiar with rust. But what is really going on when things rust? Read **How does rust work?** to find out more. As you are reading, jot down the answers to these questions in your notebook:

* What is a chemical reaction?


 * What is the definition of an anode, an electrolyte, and a cathode?


 * Can you think of anything used in everyday life that rusts and corrodes if you leave it outside to be exposed to rain?


 * What is the chemical name of rust?

||
 * Do other metals rust or otherwise oxidize?

PART II - INVESTIGATE
Oxidation and Reduction reactions have every day applications. You will choose one topic from the list below to investigate online. Clicking the topic will take you to a website that will help your investigation. You and your partner will create a whiteboard and present the information on your topic. Your whiteboard should include the following information:
 * 1) TOPIC
 * 2) How your topic uses oxidation-reduction reaction.
 * 3) The REDOX reaction equation showing loss/gain of electrons. (if shown)
 * 4) Benefits or Risks of your topic as it relates to everyday life.
