What solution will dissolves the metal gold?
Aqua regia (mixture of concentrated nitric acid and hydrochloric acid). However, nitric acid and hydrochloric acid by themselves don't dissolve gold.
Which metal doesn't react with nitric acid?
Nitric Acid cannot react with Gold alone. The only solution that can dissolve Gold is Aqua Regia; a combination of Nitric Acid and Hydrochloric Acid.
Latin name for a mixture of 3 parts hydrochloric acid and one part nitric acid?
The mixture of HNO3 and HCl in a 1:3 ratio respectively is known as "aqua regia". Although both component acids are clear, they form an orange solution when mixed. Aqua regia is highly corrosive and is most often used to dissolve gold...it's about the only thing that will.
Chemical composition for Aqua regia?
aqua regia is a solution of nitric acid+hydrochloric acid. ratio is 3:1.
What is the reaction when gold and sulfuric acid are mixed?
Gold is one of the least reactive metal. When gold is mixed with acid, it does not react or dissolve. Gold reacts only with AQUA REGIA [three parts of concentrated hydrochloric acid and one part of nitric acid.] AQUA REGIA can dissolve almost all metals.
How do you dissovle gold?
Aqua Regia will dissolve gold. Aqua Regia is a mixture of Nitric acid and Hydrochloric acid.
What acid will dissolve platinum?
Hot Aqua Regia

Can acid burn through gold?
Aqua regia, which is a mixture of nitric and hydorchloric acid, is the only acid that could dissolve gold. Gold is a very inert substance, and any other acid other than aqua regia cannot dissolve it.
Why is cynide used in gold processing and not sulfuric acid or chloride solution?
Because the solubility of gold in cyanide solution is far greater. Sulfuric won't dissolve gold at all, and hydrochloric acid will only dissolve gold when used in conjunction with nitric acid, a mixture called aqua regia, which is pricey.

What do acid do to topaz?
Most substances will react with some acid or another. Even glass will be dissolved by hydroflouric acid and even gold will dissolve in aqua regia. As for regular acids, I have put a sample of topaz in a hydrochloric acid solution and after three weeks, it was unchanged.

What solution is capable of dissolving gold?
Aqua regia, which is a mixture of two acids, will dissolve gold. Aqua regia is a mixture of concentrated nitric acid (HNO3) and concentrated hydrochloric acid (HCl), usually in a 1 to 3 ratio respectively. Aqua regia is one of the few acids that will dissolve both gold and platinum as well as other metals. Interestingly, neither hydrochloric acid nor nitric acid alone will dissolve gold, but together, they will!Both acids do different jobs. Nitric acid actually dissolves a virtually undetectable amount of gold, which reacts with the hydrochloric acid to produce ions that are much more soluble. This frees the nitric acid to dissolve the gold further, and the reaction continues.See the Web Links to the left for more information about aqua regia.
What is the chemical formula of aqua-regia?
A mixture (acid) of HCl and HNO3. Formed by mixing 3 moles of HCl and 1 mole of HNO3 i.e in the ratio 3:1. This is one of the few acids that can dissolve metals like gold and platinum. FIrst discovered by the famous Muslim scientist Jabir-bin-Haiyan(known as the father of chemistry). It is a highly-corrosive fuming yellow liquid. The name "Aqua Regia" is latin for "Royal Water". It was so named because it could dissolve the royal noble metals.Aqua regia works to dissolve gold, even though neither constituent acid will do so alone because, in combination, each acid performs a different task. Nitric acid is a powerful oxidizer, which will actually dissolve a tiny (virtually undetectable) amount of gold, forming gold ions. The hydrochloric acid provides a ready supply of chloride ions, which react with the latter, thus taking the gold out of the solution. This allows further oxidation of gold to take place, and so the gold is dissolved.
