The Copper Weights & pH 3/3/11:
A: 18.9g pH 9
B: 18.3g pH 11
C: 19.0g pH 11
D: 19.1g pH 8
E: 17.8g pH 7.5
F: 17.5g pH 4.5
Some of the metals actually increased in weight, the corrosion cannot add on to the metals, so there must have been a problem with the weights or there was still some liquid trapped in the metal. I plan to blow dry it longer, so all the liquid evaporates. The ammonia leaves a blue trace on the copper, clorox made it blackish, and the color of the water is green, like the statute of liberty. Sulfuric acid does not look like it is affecting the metal a lot, but in fact, it has the second most corrosion. Copper has the least corrosion among the three.
