Jonathan Davis’s Science Experiment HCI=Hydrochloric acid, H2SO4= Sulfuric Acid, Zn-Zinc, Cu=Copper, Sn=Tin, Pb= Lead, Fe=Iron Knew I had a few misconceptions on what happens when you bathed metals into Acids. I also just wanted to see what would happen to the metals or acids themselves.
 * __Reason of creation of experiment__**
 * __Proposal/Plan__**

Get various metals and see what kinds of metal are available. Preferably in sheet or powdered form. Get 2-4 types of acids and put the same or approximant amounts of the metals in each of the test tubes which will be filled partially filled up with different acids. After a few weeks or days, depending on what happens. I will come back to my experiments and see how each of them has changed in shape, color, and maybe smell.

Iron Power/ Granules-used in 3 test tubes Copper powder- used in 2 test tubes Lead granules/powder- used in 3 test tubes Tin granules- used in 1 test tube Zinc granules- used in 3 test tubes Hydrochloric Acid-6M Sulfuric Acid-6M 10% Acetic Acid- Molar ? 12 test tubes Test tube rack Acid strength testing Machine The Program “Logger Pro” A Laptop to display Acid Strengths

HCI + FE HCI + Cu  HCI + Pb  HCI + Zn  H2SO4 + Pb  H2SO4 + Zn  H2SO4 + Fe  H2SO4 + Cu  10% Acetic Acid + Pb  10% Acetic Acid + Zn  10% Acetic Acid + Sn  10% Acetic Acid + Fe  Results on all test tubes were completely different from what I had expected would have happened, particularly on the test tubes where the color of the acid would change into a very dark green or orange color. A few of the test tubes had had crystals growing inside of them and 2 of them had crusted over on the top. Pictures below show results…
