I putted copper pieces in vinegar but I seen not any events.Can a "long-term operations" lead to corrosion phenomena?
Yes. But very slowly. Copper reacts with most acids, if you used HCl or H2SO4 you would have seen the reaction of copper + vinegar times a billion. Vinegar is the same idea, but being a much weaker acid, the reaction is much slower.
well copper turns all green in vinegar. That could be like rusting and all of the copper just chips away
copper! aluminum is cant rust btw
depending on the strength of the vinegar, you should get a reaction with the copper. In specific, copper acetate... a green corrosion. I've read that you can speed up the process by adding baking soda to the vinegar, thus creating a breakdown of molecules and allowing the copper to bond... Don't know if it works or not... By the by, corrosion is the gradual change of molecular structure, most notably through oxidation. It's usually pretty slow.
