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 Materials Chemistry A Journal of Materials Chemistry A The Journal of Materials Chemistry A is a weekly peer-reviewed scientific journal that covers the synthesis, properties, and applications of novel materials related to energy and sustainability. It is one of three journals created after the "Journal of Materials Chemistry" was split at the end of 2012. Its first issue was published in January 2013. The journal is published by the Royal Society of Chemistry and has two sister journals, "Journal of Materials Chemistry B" and "Journal of Materials Chemistry C", which cover different materials science topics. The editor-in-chief for the "Journal of Materials Chemistry"
