Gold Compounds - an overview | ScienceDirect Topics

Gold compounds are the most toxic of the copper, silver, and gold subgroup. When gold compounds are used medically, it is found that their excretion is slow, approximately 20% in two weeks and less thereafter. The side effects include urticaria (hives), itching, purpura, and skin rashes; damage to the blood forming organs and the nervous system has also been described. The effects can be long ...

Gold - Wikipedia

The World Gold Council states that as of the end of 2017, "there were 187,200 tonnes of stocks in existence above ground". This can be represented by a cube with an edge length of about 21 metres (69 ft). At $1,349 per troy ounce, 187,200 tonnes of gold would have a value of $8.9 trillion. According to the United States Geological Survey in 2016, about 5,726,000,000 troy ounces (178,100 t) of gold has been accounted for, of which 85% remains in active use.

Facts about Gold

Among the relatively few gold compounds of practical importance are gold chloride, AuCl; gold trichloride, AuCl3; and chlorauric acid, HAuCl4. In the first compound gold is in the +1 oxidation state, and in the latter two, the +3 state. All three compounds are involved in the electrolytic refining of gold. Potassium cyanoaurate is the basis for most gold-plating baths (the solution employed ...

Chemical Properties of Gold - Science Struck

Gold tends to form an amalgamation with mercury instead of reacting to create new compounds. It is resistant to the effect of most acids and therefore does not corrode easily. Gold can however be affected by 3:1 mixture of hydrochloric acid and nitric acid, called aqua regia. So, generally speaking gold is not a highly reactive compound. Apart from acids, gold does not combine with oxygen ...

Uses of Gold in Industry, Medicine, Computers, Electronics ...

Uses of Gold in Electronics. The most important industrial use of gold is in the manufacture of electronics. Solid state electronic devices use very low voltages and currents which are easily interrupted by corrosion or tarnish at the contact points. Gold is the highly efficient conductor that can carry these tiny currents and remain free of corrosion. Electronic components made with gold are ...

Gold Compounds - Mineral Processing & Metallurgy

2016-10-24· Compounds of Gold with the Halogens. Gold forms two series of compounds with the halogens, the general formulae being AuR and AuR3 respectively. Supposed compounds having the formula AuR2 have been described, but are probably mixtures of the series denoted by AuR and AuR3. All these bodies are very unstable, existing throughout only low ranges of temperature, whether in the dry state or in ...

[The Pharmacology of Gold Compounds] - PubMed

The new gold compound triethylphosphine gold (auranofin) can be partially absorbed in the gut following oral administration due to its higher lipophilic nature. This is probably also the main cause for the differences in kinetic properties versus the parenteral gold compounds. Following administration of auranofin, there are lower concentrations of gold in blood and organs; 95% of the gold is ...
