Thank you for the easiest, safest test. Rated this article:. Maggie Mae Oct 8, Helped me to understand markings on my jewellery and I looked up the makers and found who made the Jewellery.
Very informative. Lucylulu Magoo Jul 20, I thought it was white gold and your article confirmed this.

Most often the native platinum is found in secondary deposits in alluvial deposits. Another large alluvial deposit is in the Ural Mountains , Russia, and it is still mined.
In nickel and copper deposits, platinum-group metals occur as sulfides e. Pt,Pd S , tellurides e. PtBiTe , antimonides PdSb , and arsenides e.
PtAs 2 , and as end alloys with nickel or copper. Platinum arsenide, sperrylite PtAs 2 , is a major source of platinum associated with nickel ores in the Sudbury Basin deposit in Ontario , Canada.
The mine ceased operations in In , chromites were identified in the Bushveld region of South Africa, followed by the discovery of platinum in In the Sudbury Basin, the huge quantities of nickel ore processed make up for the fact platinum is present as only 0.
Smaller reserves can be found in the United States,  for example in the Absaroka Range in Montana. Large platinum deposits are present in the state of Tamil Nadu , India.
Platinum exists in higher abundances on the Moon and in meteorites. Correspondingly, platinum is found in slightly higher abundances at sites of bolide impact on Earth that are associated with resulting post-impact volcanism, and can be mined economically; the Sudbury Basin is one such example.
Hexachloroplatinic acid mentioned above is probably the most important platinum compound, as it serves as the precursor for many other platinum compounds.
By itself, it has various applications in photography, zinc etchings, indelible ink , plating, mirrors, porcelain coloring, and as a catalyst.
Treatment of hexachloroplatinic acid with an ammonium salt, such as ammonium chloride , gives ammonium hexachloroplatinate ,  which is relatively insoluble in ammonium solutions.
Heating this ammonium salt in the presence of hydrogen reduces it to elemental platinum. Potassium hexachloroplatinate is similarly insoluble, and hexachloroplatinic acid has been used in the determination of potassium ions by gravimetry.
When hexachloroplatinic acid is heated, it decomposes through platinum IV chloride and platinum II chloride to elemental platinum, although the reactions do not occur stepwise: .
All three reactions are reversible. Platinum II and platinum IV bromides are known as well. Platinum hexafluoride is a strong oxidizer capable of oxidizing oxygen.
Platinum IV oxide , PtO 2 , also known as ' Adams' catalyst ', is a black powder that is soluble in potassium hydroxide KOH solutions and concentrated acids.
Unlike palladium acetate , platinum II acetate is not commercially available. Where a base is desired, the halides have been used in conjunction with sodium acetate.
Zeise's salt , containing an ethylene ligand, was one of the first organometallic compounds discovered.
Dichloro cycloocta-1,5-diene platinum II is a commercially available olefin complex, which contains easily displaceable cod ligands "cod" being an abbreviation of 1,5-cyclooctadiene.
The cod complex and the halides are convenient starting points to platinum chemistry. Cisplatin , or cis -diamminedichloroplatinum II is the first of a series of square planar platinum II -containing chemotherapy drugs.
These compounds are capable of crosslinking DNA , and kill cells by similar pathways to alkylating chemotherapeutic agents. Archaeologists have discovered traces of platinum in the gold used in ancient Egyptian burials as early as BC.
For example, a small box from burial of Shepenupet II was found to be decorated with gold-platinum hieroglyphics. It is quite possible they did not recognize there was platinum in their gold.
The metal was used by pre-Columbian Americans near modern-day Esmeraldas, Ecuador to produce artifacts of a white gold-platinum alloy.
Archeologists usually associate the tradition of platinum-working in South America with the La Tolita Culture circa BC - AD , but precise dates and location is difficult, as most platinum artifacts from the area were bought secondhand through the antiquities trade rather than obtained by direct archeological excavation.
The resulting gold-platinum alloy would then be soft enough to shape with tools. It was often simply thrown away, and there was an official decree forbidding the adulteration of gold with platinum impurities.
Ulloa and Juan found mines with the whitish metal nuggets and took them home to Spain. Antonio de Ulloa returned to Spain and established the first mineralogy lab in Spain and was the first to systematically study platinum, which was in His historical account of the expedition included a description of platinum as being neither separable nor calcinable.
Ulloa also anticipated the discovery of platinum mines. After publishing the report in , Ulloa did not continue to investigate the new metal.
In , he was sent to superintend mercury mining operations in Huancavelica. In , Charles Wood,  a British metallurgist , found various samples of Colombian platinum in Jamaica, which he sent to William Brownrigg for further investigation.
In , after studying the platinum sent to him by Wood, Brownrigg presented a detailed account of the metal to the Royal Society , stating that he had seen no mention of it in any previous accounts of known minerals.
Style Variations: bold - light - outlined - colorable. General Alchemy description Alchemy, which gained significant popularity in Medieval Europe, is the precursor to modern-day chemistry, philosophy and scientific method.
Alchemists performed experiments, attempting to turn base metals, such as lead, into gold. They sought to develop an elixir that would grant immortality or eternal life, as well as a cure-all medicinal panacea.
