Jewelry Lab report Electroplating
Purpose:
Theory of electroplating. 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 electroplating.
Electroplating occurs at the _______.
Procedure: Use my short list and the drawing
include thet cleaning solutions and the temperature required for
any hot plates.
Include a detailed drawing of the set up for electroplating metals.
Reactions and Calculations
Write the half reactions for just Ni . Label the number of electrons
transferred. Why was energy required for electroplating?
Conclusion:
1. Restate purpose
2. What was your finished product? Draw and color your product.
3. What other items could be plated and with what metal?
4. How could the experiment be improved?
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?
