Chemical Properties. Copper Oxide is a mixed oxidation state oxide, with both Cu + (cuprous) and Cu 2+ (cupric) oxidation states present. Its reactivity can be traced to its basic nature, especially when subjected to acidic conditions. Copper Oxide is insoluble in water but can dissolve in acid to generate copper salts.

But back to the copper: It turns out that the best way to oxidize a big batch of copper is to space it out — at least four blocks of air between each copper block will significantly speed up the rate at which they turn from orange to green (although the proper term is "verdigris", don'tcha know). Five blocks of air between each block will be ...
