Dentistry and electronics are two of the industries that uses pure gold due to the quality of the resistance in corrosion and the quality you get as a conductor of electricity. Pure gold is more chemically unreactive than most metals but can be attacked by a mixture of acids that form what is called chlorauric acid and by cyanide that has an alkaline solution.
Gold does react with amalgam alloys, which is the dissolving of gold into mercury. Nitric acid dissolves silver and base metals, therefore gold does not dissolve in nitric acid. The gold standard test is used to determine the real value and since Nitric acid has been used to confirm the presence of gold in certain items, this is where they get the acid test or gold standard test from.
Did you know that a single gram can be made into a sheet of 1 square meter? It can also be made into an ounce of 300 sq. feet. You can get a translucent thin sheet when constructed down, which is where they get the Gold leaf. Melting point can be controlled by alloys being produced to change the hardness and metallurgical properties. Gold readily creates alloys with many other metals. These alloys can be produced to modify is also an excellent choice in the conductor of heat and electricity and reflects infra red radiation. Gold is not affected by the air and moisture as well as corrosive reagents. This makes it ideal for the making of coins and gold jewelry as well as giving a protective coat of protection. Gold does however dissolve in alkaline solutions of potassium cyanide and in mercury, forming a gold-mercury amalgam.
When you add any other metal as the reducing agent, the gold ions in solutions are reduced and precipitated. The added metal is oxidized and dissolves allowing the gold to be displaced from solution and be recovered as a solid precipitate.
You can not taste the pure gold that is high in quality. It is tasteless which makes it resistant to corrosion.
In closing, pure gold is very dense which weighs in at 19300 kg in cubic meter reading and to give you comparison to lead, lead has a density of 11340 kg.
