Electrochemistry

=Electrochemistry and Energy=

Many devices run on battery power. But what creates the energy in a battery? The chemistry of redox reactions is a source of the electric current that makes these devices work.

In this activity you will apply your understandings of redox reactions and use some of your knowledge about acid-base chemistry to the practical applications of these reactions. You will investigate typical batteries and rechargeable batteries.

The first applet you will use is a tutorial for a **__zinc-copper__** cell. Follow the tutorial and answer the questions on your worksheet. Choose [|Section 17.1 Zinc-Copper Cell] and click on View Tutorial at the right. **PART II** The second applet you will use is a tutorial for a **__nickel-cadmium__** cell. Follow the tutorial and answer the questions on your worksheet. Choose [|Section 17.3 NiCad Battery] and click on View Tutorial at the right.
