Alfa Chemistry offers an extensive catalog of building blocks, reagents, catalysts, reference materials, and research chemicals in a wide range of applications, such as aucl3. Gold(III) chloride, traditionally called auric chloride, is a chemical compound of gold and chlorine. With the molecular formula Au2Cl6, the name gold trichloride is a simplification, referring to the empirical formula, AuCl3. The Roman numerals in the name indicate that the gold has an oxidation state of +3, which is common for gold compounds. There is also another related chloride of gold, gold(I) chloride (AuCl). Chloroauric acid, HAuCl4, the product formed when gold dissolves in aqua regia, is sometimes referred to as "gold chloride" or "acid gold trichloride". Gold(III) chloride is very hygroscopic and highly soluble in water as well as ethanol. It decomposes above 160 °C or in light.

This is a really great question Eric. Electron configurations are always such a mess. I never get why gen chem books have to show the Cr and Cu anomalies, but that is a topic from another forum you started (https://www.ionicviper.org/forum/anomalous-configurations-such-cr-and-cu). I'll admit, I haven't given this a ton of thought, but I think I like Lutetium as the first 6d metal. The reason for me is that Hafnium is then filling the same orbitals that Lutetium is, the 6d. If you put Lanthanum in group the next element, Cerium, starts filling a completely different orbital, the 4f. Unfortunately, this logic kind of goes out the window with Lawrencium. O well, it isn't perfect. If anyone else has similar thoughts (or conflicting ones) I would sure love to hear them. I think it would be easy to change my mind. In fact, I hope you do because my mnemonic for memorizing group 3 is Sc(ott) Y(ou're) La(te) Ac(k) and I would hate to have to change it.

Eric,

Has anything been concluded by the IUPAC task force yet? Keep us informed!
