Experiment Cu: vinegar, vinegar + salt, solvent

[Thrilla]

Just to see how copper reacts to these 3 WC component cleaning agents, I'm doing an experiment.

10:00 AM PST Feb 11, 2007
Each vial contains 4 copper wires and 1 copper strip.
1: vinegar
2: vinegar with some salt, shaked up
3: paint thinner (solvent, couldn't find any alcohol)
Room temperature: 20.0'C





10:30AM: so far nothing is going on in #1, tiny bubbles are forming on #2, and nothing #3. g2g work back at 6PM
5:00PM: It's been 6:30 hours, nothing is going on still. The bubbles on #2 are gone.
8:40PM: sample liquids drained so Cu are exposed to air, samples placed outside, overnight temp 2'C (can't stand the smell of vinegar and paint thinner lol)



Day2 8:15AM: vial #2's liquid is slightly blue-ish, the other 2 still have nothing going on.
