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
Journal of Physical Chemistry A a further split, with "Journal of Physical Chemistry C" now being dedicated to the burgeoning fields of nanotechnology, molecular electronics, and related subjects. "The Big Bang Theory" character, Sheldon Cooper, fictionally appeared on the cover of one of the journals. Journal of Physical Chemistry A The Journal of Physical Chemistry A is a scientific journal which reports research on the chemistry of molecules - including their dynamics, spectroscopy, kinetics, structure, bonding, and quantum chemistry. It is published weekly by the American Chemical Society. Prior to 1997 the title was simply Journal of Physical Chemistry. Owing to the ever-growing amount of
