Silver gold compound

Most silver salts, with the exception of AgNO3, AgF, and AgClO4, have poor solubility. Silver forms complex compounds, most of which are soluble in water and many of which have practical uses in chemical technology and analytical chemistry. Examples are the complex ions [Ag (CN)2] -, [Ag (NH3) 2]+, and [Ag (SCN)2] -.

Silver compounds include such familiar substances as silver chloride (AgCl), silver bromide (AgBr), and silver iodide (AgI). Each of these salts is used extensively in photography . Silver chloride serves as the light-sensitive material in photographic printing papers and, together with silver bromide, in certain films and plates. Gold;silver | AgAu | CID 25195668 - structure, chemical names, physical and chemical properties, classification, patents, literature, biological activities, safety Gold is insoluble in nitric acid, which dissolves silver and base metals, a property that has long been used to refine gold and to confirm the presence of gold in metallic objects, giving rise to the term acid test. Gold also dissolves in alkaline solutions of cyanide, which are used in mining and electroplating. No. There are elemental minerals, like gold, silver, and copper, appearing in crystalline form. The bulk of minerals, however, are compounds of two or more elements.
