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.
Expected Results. After adding the ammonia, a whitish precipitate will form at the top of the copper II sulfate solution. As more ammonia is added, the color on top of the liquid will change to a deeper darker blue. As the hydrogen peroxide is added, the dark blue area at the top of the solution will turn dark green and a dark precipitate will form.
