Usage And Synthesis
Chloroauric acid

Chloroalic acid is also known as "gold chloride", "gold chloride tetrahydrate". Chemical formula is HAuCl4 • 4H2O. Molecular weight is 411.85. It is a yellow needle crystal. It is toxic and corrosive. It is easily soluble in water, and soluble in ethanol and ether, and slightly soluble in chloroforrm. Anhydrous chloroauric acid can be crystallized from the ethanol solution. It will decompose under heat condition, and decompose into gold trichloride at 120 ° C. Exposure of it leads to black spots. In alkaline solution, it reacts with KI to precipitate brown gold. In the acidic solution, it generates "cinnamon purple in the case of tin dichloride. Its aqueous solution was purple after dealing with methyl orange, and it turns green after 1 to 3 drops of hydrochloriic acid, and then it becomes lavender after gold salt solution. We get gold hydroxide precipitation after adding cold potassium hydroxidee solution. It was reduced to gold powder with sulfur dioxidee.
