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.
Silver nitrate reacts with salt to produce a dark colored residue. Since salt is often part of the latent print residue, this reaction allows yet another way of development or enhancement of prints. It must follow ninhydrin if sequential enhancements will be applied. If salt is present in the substrate, the entire object will darken. Silver nitrate reacts with light to darken also.
