Oscillating Chemical Reactions - Inside Mines

2010-11-9  Oscillating reactions are among the most fascinating of chemical reactions. In one type of reaction, a mixture of chemicals goes through a sequence of color changes, and this sequence repeats periodically. In another, the mixture periodically emits a burst of gas, foaming up. To many, oscillating reactions are engaging examples of "chemical magic."

Silver Ag - PubChem

Silver is a naturally occurring element. It is found in the environment combined with other elements such as sulfide, chloride, and nitrate.Pure silver is "silver" colored, but silver nitrate and silver chloride are powdery white and silver sulfide and silver oxide are dark-gray to black. Silver is often found as a by-product during the retrieval of copper, lead, zinc, and gold ores.
