Jewelry Lab report Anodizing

Purpose:

Theory of anodizing. This information is on my website. Got to the syllabus (table of contents) and find the lab under electrochemistry unit. Do not copy this information directly. Put it into your own words. Describe the electrochemical technique of anodizing.
Anodizing occurs at the _______. Include the notes - drawing of the layers of TiO2 and how that affects the color.



Procedure. Keep this brief, the drawing will tell everything.
Include a detailed drawing of the set up for anodizing jewelry all the cleaning and rinsing steps and voltage used for your color.



Conclusion:
1. Restate purpose
2. See procedure above.
3. What was your finished product? Draw and color your product.
4. How were different colors obtained?
5. What other items could be anodized and with what metal?


Personal evaluation of the activity:
Was the jewelry making just fun or did you really understand and learn more about electrochemistry by making the jewelry?
Did you learn more about jewelry or about chemical principals?
Did the activity make you want to learn more about chemistry or science in general?
