Amalgam (chemistry) with copper. A nitric acid solution of salts under investigation is applied to a piece of copper foil, and any mercury ions present will leave spots of silvery-coloured amalgam. Silver ions leave similar spots but are easily washed away, making this a means of distinguishing silver from mercury. The redox reaction involved where mercury oxidizes the copper is: Dental amalgam has been studied and is generally considered to be safe for humans, though the validity of some studies and their conclusions have been questioned. Amalgam (chemistry) An amalgam is an alloy of mercury with another metal, which may be a
IUPAC Inorganic Chemistry Division the periodic table. For the scientific end educational community the work on isotopic abundances and atomic weights is of fundamental importance as these numbers are continuously checked and updated. The division has the following subcommittees and commissions: List of Running Projects of IUPAC Division II The Inorganic Chemistry Division was a partner in the 2011 Global Chemistry Experiment “Water: A Chemical Solution” that took part during the International Year of Chemistry.
