It was referenced in European writings as early as 16th century, but it was not until Antonio de Ulloa published a report on a new metal of Colombian origin in that it became investigated by scientists.
Platinum is used in catalytic converters, laboratory equipment, electrical contacts and electrodes, platinum resistance thermometers, dentistry equipment, and jewelry.
Because only a few hundred tonnes are produced annually, it is a scarce material, and is highly valuable and is a major precious metal commodity.
Being a heavy metal, it leads to health issues upon exposure to its salts, but due to its corrosion resistance, it is not as toxic as some metals.
Compounds containing platinum, most notably cisplatin, are applied in chemotherapy against certain types of cancer.
Graphical characteristics: Symmetric , Closed shape , Monochrome , Contains both straight and curved lines , Has no crossing lines.
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.
In , Henrik Scheffer published a detailed scientific description of the metal, which he referred to as "white gold", including an account of how he succeeded in fusing platinum ore with the aid of arsenic.
Scheffer described platinum as being less pliable than gold, but with similar resistance to corrosion. Carl von Sickingen researched platinum extensively in He succeeded in making malleable platinum by alloying it with gold, dissolving the alloy in hot aqua regia , precipitating the platinum with ammonium chloride , igniting the ammonium chloroplatinate, and hammering the resulting finely divided platinum to make it cohere.
Franz Karl Achard made the first platinum crucible in He worked with the platinum by fusing it with arsenic, then later volatilizing the arsenic.
Because the other platinum-family members were not discovered yet platinum was the first in the list , Scheffer and Sickingen made the false assumption that due to its hardness—which is slightly more than for pure iron —platinum would be a relatively non-pliable material, even brittle at times, when in fact its ductility and malleability are close to that of gold.
Their assumptions could not be avoided because the platinum they experimented with was highly contaminated with minute amounts of platinum-family elements such as osmium and iridium , amongst others, which embrittled the platinum alloy.
Alloying this impure platinum residue called "plyoxen" with gold was the only solution at the time to obtain a pliable compound, but nowadays, very pure platinum is available and extremely long wires can be drawn from pure platinum, very easily, due to its crystalline structure, which is similar to that of many soft metals.
Chabaneau succeeded in removing various impurities from the ore, including gold, mercury, lead, copper, and iron. This led him to believe he was working with a single metal, but in truth the ore still contained the yet-undiscovered platinum-group metals.
This led to inconsistent results in his experiments. At times, the platinum seemed malleable, but when it was alloyed with iridium, it would be much more brittle.
Sometimes the metal was entirely incombustible, but when alloyed with osmium, it would volatilize. This started what is known as the "platinum age" in Spain.
Platinum, along with the rest of the platinum-group metals , is obtained commercially as a by-product from nickel and copper mining and processing.
During electrorefining of copper , noble metals such as silver, gold and the platinum-group metals as well as selenium and tellurium settle to the bottom of the cell as "anode mud", which forms the starting point for the extraction of the platinum-group metals.
If pure platinum is found in placer deposits or other ores, it is isolated from them by various methods of subtracting impurities.
Because platinum is significantly denser than many of its impurities, the lighter impurities can be removed by simply floating them away in a liquid.
Platinum is paramagnetic , whereas nickel and iron are both ferromagnetic. Auto Refresh Is. All market data contained within the CME Group website should be considered as a reference only and should not be used as validation against, nor as a complement to, real-time market data feeds.

Drop the acids on the different metal lines. Select an acid test from your kit and carefully drop a small amount of acid onto one of the drawn lines.
Make sure that you don't mix the different acids together or you'll affect your results. Most tests have acids specifically for silver.
However, you can also use an karat gold testing acid to identify pure or sterling silver. Observe the reaction of the acid. These reactions can take anywhere from a second to a minute.
If the line completely dissolves, the test fails. However, if your line doesn't dissolve, the metal is pure. If you use the karat gold acid test to test on silver, the line will turn a milky white color.
If you doubt your results, test the jewelry again to be sure. Method 3 of Use a silver testing solution on large, hardy pieces of jewelry. Avoid using this acid on delicately decorated jewelry.
The acid will corrode any part of the surface that it touches. If you purchased an acid scratch testing kit, use the silver testing solution included.
Otherwise, purchase the silver testing solution online or from a jewelry supply store. Test the jewelry.
Drop a small amount of the silver testing solution onto the metal. Choose a hidden area of the jewelry to test. For example, if you're testing a large cuff bracelet, drop some acid on the inside of the bracelet.
Alternatively, if you're testing a flat, chunky necklace, drop acid on the back of one of the necklace sections.
Wear gloves to protect your hands and work over a towel to protect your workspace. Don't drop acid on clasps or other important sections.
The acid may damage any smaller workings in the jewelry. Observe the reaction. The acid will appear dark brown or clear at first and then turn into a different color.
The new color will indicate the purity of the metal. If the solution turns white, the metal is Clean the acid from your jewelry.

English and French jewelry makers have used hallmarks since the 14th century, but American makers have never used them on platinum per se.
French jewelry makers utilized the eagle head and dog head hallmarks for platinum after , when they formally recognized it as a precious metal.
Hallmarks may include maker's marks—the proprietary mark of a smith—expressed by a name or artistic mark stamped on the piece.
