中文百科

三氯化金 Gold(III) chloride

(重定向自Auric chloride)

三氯化金,俗称氯化金,是最常见的无机金化合物,化学式是AuCl3。名称中的罗马数字表明金的化合价为+3,这是它众多化合物中最为稳定的价态。金亦会形成另一种氯化物——氯化亚金(AuCl),它没有AuCl3稳定。另外,把金溶于王水中便会产生氯金酸(HAuCl4),有时也会非正式地称为:「氯化金」、「三氯合金酸」或是「三水合氯化金(III)」

氯化金(III)吸湿性很强,极易溶于水及乙醇。温度高于160 °C或光照时会分解,并产生多种有大量配体的配合物。

Gold(III) chloride 三氯化金

(重定向自Auric chloride)

Gold(III) Chloride, traditionally called auric chloride, is a chemical compound of gold and chlorine. With the molecular formula AuCl3, the name gold trichloride is a simplification, referring to the empirical formula. 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.
