Evidence of Work:
For this project, we had to each come up with an art piece that is related to chemistry and is connected to the other art pieces in our group. My group decided to make art, using a chemical reaction to draw the designs. We then decided to have our designs each related to a different subject in science, mine being biology. |

Procedure:
1. Cover both sides of a piece of galvanized iron in masking tape.
2. Draw a design that is related to a subject in science, i.e. biology.
3. Cut out the parts of your design that you want to be colored.
4. Pour 6 M hydrochloric acid into a container large enough to fit the entire sheet of metal.
5. Completely submerge the sheet of metal into the hydrochloric acid.
6. Once the rapid bubbling stops, remove the metal from the hydrochloric acid. Rinse with water and dry with paper towels.
7. Clean the exposed area of the design with an eraser.
8. Pour cupric nitrate into a beaker.
9. Dip cotton swabs into the cupric nitrate and rub it over the exposed areas.
10. Rinse with water and dry with paper towel.
11. Remove the masking tape.
Chemistry:
HCL acid or hydrocloric acid removes the zinc coat from the iron. (Single Replacement Reaction)
Zn(s) + 2HCL(aq) >> ZnCl2(aq) + H2(g)
Cupric nitrate reacts with the exposed iron where the zinc coat has been removed. (Single Replacement Reaction)
Fe(s) + CU(NO3)2(aq) >> Fe(NO3)2(aq) + Cu(s)

Reflection:
Overall this project went pretty well, however there were a few pits that went along with the peaks.One pit was that we took a while to decide on what we were going to do for the project. Once we decided that we were going to do a design on a sheet of metal we had to decide what chemical reaction we wanted to do. We tried to do multiple different reactions but the only one that worked was the once we did as a class. Another pit was that the tape did not stay on very well in some parts so the zinc got removed in areas that it wasn't supposed to. This resulted in a design where parts bleed together on mine.
One peak of this project was that we were all able to finish the project despite the delay in the beginning. We would not be able to do the reaction at home so it is a good thing that we got through that in time. Another peak was that since we all knew how the project worked by the end we were able to present without ever practicing our slides before.
