vopsire in camp electrostatic/electroliza, sau cum faci bateriile sa arate ca alea din cupru Options

[guerilla]

any advice?

LE> sau electroliza. sau orice alt procedeu numa sa fie cupru

Cuprul cocleste inclusiv in aliaje, si da, e verde, si se spune ca e toxic. D-aia sint statuile verzi. Sau negre, depinde de expunere. Si alte obiecte, de exemplu centi americani sint multe ori verzi.
La cantina freaca aia oalele de le ies ochii zilnic, deci e alta treaba. Lasa-le nemiscate o luna sa vezi cum arata. Robinetii si chiuveta au adincituri in care e cam greu sa intri cu frecatul.

Copper is a metal that does not react with water (H2O), but the oxygen of the air will react slowly at room temperature to form a layer of brown-black copper oxide on copper metal.

It is important to note that in contrast to the oxidation of iron by wet air that the layer formed by the reaction of air with copper has a protective effect against further corrosion. On old copper roofs a green layer of copper carbonate, called verdigris, can often be seen. A notable example of this is on the Statue of Liberty.

Verdigris is the common name for the green coating or patina formed when copper, brass or bronze is weathered and exposed to air or seawater over a period of time. It is usually a basic copper carbonate, but near the sea will be a basic copper chloride.[1] If acetic acid is present at the time of weathering, it may consist of copper(II) acetate.

Hai ma dati-o naibii, parca n-ati trecut prin clasa a 7a . Sau n-ati vazut si voi nimica de cupru.
