Commonly known are applications in jewellery, coins and cutlery. In electronics, silver is applied for outlets. Amalgam is a silver alloy with a high mercury content. It is applied for example in copper, nickel and tungsten alloys. It is known for its high thermal and electrical conductivity, its reflective power and its white colour. Naturally occurring pure silver is extremely rare and is probably formes through the following reaction mechanism:īesides gold, silver is the most bendable of all metals. In soils it is mainly present in sulphide minerals. Silver mainly occurs in argenite and stephanite, from which it is released through weathering. Silver fluorides are generally water soluble, but other silver halogens are not. Silver nitrate has a water solubility of 2450 g/L. For example, silver chloride has a water solubility of 0.1 mg/L, maximum. Some other sulphur compounds are more or less water soluble. This also applies to a number of silver compounds, such as silver sulphide. Under normal conditions silver is water insoluble. Solubility of silver and silver compounds Moreover, it is acid and base resistant, but it corrodes when it comes in contact with sulphur compounds. In what way and in what form does silver react with water? In oyster tissue concentrations of approximately 890 ppm (dry mass) were found.ĭissolved in water silver mainly occurs as Ag + (aq), and in seawater as AgCl 2 - (aq). The phytoplankton concentration is 0.1-1 ppm (dry mass), leading to a 10 4-10 5 bio concentration factor in seawater. River water generally contains approximately 0.3-1 ppb of silver. Silver (Ag) and water Silver and water: reaction mechanisms, environmental impact and health effects Seawater contains approximately 2-100 ppt of silver, and the surface concentration may be even lower.
