It is true some food products labeled as baby carrots are made by cutting down larger roots, and that these items can be treated with chlorine during processing. However, itâs not true thereâs anything wrong with the larger carrots theyâre made from, or that the resultant vegetables reach consumers in a chlorine-soaked state.
The silver is reduced to elemental silver and the copper is oxidized to copper(II): Cu(0) + 2AgNO 3 = Cu(NO 3) 2 + 2Ag(0). The silver crystallizes at the surface of the copper and the copper wire quickly becomes coated with a bunch of elemental silver.
Copper turns green because of an oxidation reaction; that is, it loses electrons when exposed to water and air. The resulting copper oxide is a dull green. This oxidation reaction is the reason the copper-plated Statue of Liberty is green rather than orange-red. According to the Copper Development Association, a weathered layer of copper oxide only 0.005 inches (0.127 millimeters) thick coats Lady Liberty.
