![]() Gold(I) chloride may irritate the skin and eyes, damage kidney function, and reduce white blood cell counts. Addition of Sodium dithionite (Na2S2O4) to aqueous carbon tetrachloride solutions (650 mg/L) resulted in CCl4 concentrations lower than 2.5 mg/L after 2.5. Name:sodium tetrachloroaluminate,CAS.Molecular Fomula:AlCl4Na,Molar Mass:191.78,Density:2.01 g/mL at 25 C (lit.),Melting Point:185 C (lit. Reaction with potassium bromide yields potassium auric bromide and potassium chloride with separation of metallic gold:ģ AuCl + 4 KBr → KAuBr 4 + 2 Au + 3 KCl Safety At room temperature, it exists as a golden-orange solid. It exists in the anhydrous and dihydrate states. The sodium reduction of titanium tetrachloride is also used in the Armstrong. ![]() It is composed of the ions Na+ and AuCl4. The inability to develop either a recycle loop for the sodium chloride or the use of byproduct chlorine from the Downs cell in the carbochlorination of rutile, can have a negative effect on the economics of sponge production by this process. This conversion is key to the Miller process, which is widely used for the purification of gold. Sodium tetrachloroaurate is an inorganic compound with the chemical formula NaGold(I) chloride - Wikipedia4. When heated with water, the compound dispropotionates to metallic gold and gold(III) chloride in an autoredox reaction:Īt still higher temperatures, around 500 ☌, all gold chlorides convert to gold. Gold(I) chloride is prepared by thermal decomposition of gold(III) chloride.Īlthough there is a region of stability at higher temperatures at the appropriate chlorine vapor pressures, the compound is metastable at ambient conditions. Gold(I) chloride is a compound of gold and chlorine with the chemical formula AuCl. ![]()
