     Application: [AuCl₄]^- ions contained in aqueous solution of chloro-auric acid are used to produce many salts (X=F, Cl, Br, I, CN, SCN, NO₃) containing AuX4 - ions, which can be used for local gold plating of semiconductor and integrated circuit lead frames, as well as gold plating of printed circuit boards, electronic connectors and other electrical contact elements. Red glass can also be made. Used as an analytical reagent, especially for the microanalysis of rubidium and cesium and the measurement of alkaloid composition. Also used in photographic materials. Chloroaurates, especially NaAuCl4 (produced by the reaction of AuCl₃ with NaCl), can replace the toxic mercury (II) salt as the catalyst for the alkyne reaction. At the same time, chloroauric acid has an important application in the preparation of nano-gold. Generally, fluorescence nano-gold prepared by chloroauric acid is directly reduced by reducing agent, which has an important application in analytical chemistry.
