Damien, Sam, Kendra, and I got a 30cm piece of copper wire cleaned it off, coiled it, and put it in a test tube. Our coil weighed 3.443 grams. We poured .995 grams of silver nitrate into the test tube with the copper wire. Then we added distilled water up to 2 cm from the top of the test tube. We covered the test tube with parafilm, and waited a few days. After waiting , we weighed a piece of filter paper to be 1.45 grams, and set it up with a funnel to separate the the silver. We removed the silver, copper, and waste from the tube. We got as much silver as we possibly could onto the filter paper, the waste in another beaker, and the copper coil we let dry on a paper towel. We let everything dry overnight. The next day we measured the copper to be 3.227 grams, and the filter paper/silver to be 2.175 grams. This means that .216 grams of copper reacted with the silver nitrate, and produced .455 grams of silver.
