What can cause copper to turn black?

When the layer got thick, i.e continuous oxidation because of dry air in the surrounding, cuprous oxide will convert into cupric oxide. This oxide will be black in color. This is the chemical reason behind the black color formation of copper.

Can you paint copper black?

Generally speaking you shouldn’t paint copper or copper pipe, but you can. The paint will tend to separate from copper, and if the copper corrodes it might push the paint off even more. Also paint buckling over the copper might create a cavity where moisture can sit and help the copper to corrode faster.

Do metals react with acetic acid?

Acetic acid is mildly corrosive to metals including iron, magnesium, and zinc, forming hydrogen gas and salts called acetates: Mg + 2 CH3COOH → (CH3COO)2Mg + H.

What acid will dissolve copper?

Copper metal “dissolves” in nitric acid (HNO3). Actually, the nitrate ion oxidizes the copper metal to copper (II) ion while itself being transformed to NO2 gas in the process, the copper (II) ion then binds to six water molecules.
