Objectives:
1. Explain the parts and chemical reactions in an electrolytic cell.
2. Distinguish between electrolytic and electrochemical cells, and list some applications of each.
3. Describe how commercial cells produce an electric current; explain the process of corrosion.
An electrolytic cell is a non-spontaneous reaction (- Eo total) that is connected to a battery to provide the energy for the reaction.
Here is a video providing an overview of electrolytic cells:
Here is another video briefly describing an electrolytic cell:
This link is to several pages of notes, and the last page contains a worksheet:

This page has questions AND answers, but it's a useful overview:

Here's a simple worksheet focusing on electrolysis:

This is a link to a summary/overview but then has various worksheets about redox, ending with worksheets on electrolysis:

I've never made a lemon battery, but it's an interesting idea (btw it doesn't have to be performed in a lemon...)
Here is another electrolytic demonstration idea:

Here is a page describing how a battery works:

Here is an interesting video demonstrating how electrolysis can be used to counteract the effects of rusting on tools:
Looking at my schedule, I will post Wednesdays and Sundays through the end of May (mainly about organic chemistry), and as of June, I will post on Sundays. My posts will be in the evenings from now on.
I am selling my lab book "Chemistry on a Budget" at amazon.com for only $20! Check it out:
http://www.amazon.com/Chemistry-Budget-Marjorie-R-Heesemann/dp/0578129159/ref=sr_1_1?s=books&ie=UTF8&qid=1389410170&sr=1-1&keywords=chemistry+on+a+budget
Each lab is presented with two possible report formats -- both labs use the same procedure but each has a different conclusion -- one with 10 questions to be answered as a conclusion, the other with a full laboratory report required. This gives the teacher the option of what type of report is desired, and each version is designed to be just two pages. This way the teacher can photocopy just one 2-sided page per student (saves paper).
*I'd love to hear from you! Your feedback would really help me to focus on your needs! There should be a "Contact" form below, or click on the "Contact" tab on the top right of this page.
Have a good week!
