Chloroauric acid Use and Manufacturing
The HCl plus the HNO2 (hydrochloric and nitric acids) are combined to produce agua regia acid, which is the only acid that can dissolve gold.Chlorine acid is mainly used for alkaloid determination, electroplating gold, photography, gold powder, porcelain coloring, red glass manufacturing, special ink and treatment of tuberculosis. It can also be used as analytical reagent, such as microanalysis of rubidium (Rb) and cesium (Cs). It is used for semiconductor, electronic connector and local gold
