No. Gold will dissolve in solutions capable of oxidizing it (turning into Au3+ by stripping off 3 electrons). All HCl has available to oxidize the gold is H+ ions, which would form H2(g) when reduced (gaining 2 electrons). To tell whether or not something will be oxidized, you have to look at its oxidation or reduction potentials. For the standard reduction potential for Au3+ ions to form Au is 1.50V, which means that this is a relatively favorable process. To reverse the process and turn Au into Au3+ (oxidation) would have a negative oxidation potential: Au --> Au3+ + 3 e- Eo = -1.50V So to make this happen (i.e. dissolve gold) you would need something that wanted to be reduced with a potential greater than 1.50V. H+ ions don't cut it... they have a reduction potential of 0.00V: 2 H+ + 2 e- --> H2(g) Eo = 0.00 V So HCl cannot dissolve gold.

LaoPure gold does not dissolve in hydrochloric acid because it is a noble metal. However, aqua regia, a mixture of hydrochloric acid and nitric acid, can dissolve gold due to the oxidizing power of nitric acid.
Gold is one of the least reactive metals(if u chck the reactivity serise)..so it will not react with HCL....but Royal Water or Aqua regia which is a highly fuming, corrosive mixture whch contains conc. nitric acid and conc. hydrochloric acid in the ratio 1:3 can even dissolve gold which can be later extracted by various means...(Many people use this to their own advantage!!! -- tk gold ornaments frm ppl in promise to mk them shiny,dip the ornaments in aqua regia,whc does mk them shiny bt also reduces the weight as gold dissolves into Aqua regia.....they later extract the gold from Aqua Regia)
No. Gold will be unreactive. However.... Royal water...aqua regia can be made by mixing 1 part Nitric acid with 3 parts hydrochloric acid. This cocktail will now dissolve your gold. With Gold hovering around $1220 an ounce.....I suggest you divert your attention to other more constructive things!
Gold (Au) does not react with acid base or neutral substance. It is one of the least reactive element.
Aqua regia (one part nitric acid to three parts hydrochloric--VERY dangerous stuff!) will dissolve gold, but a single acid cannot.

Does gold dissolve in hydrochloric acid?
Yes, gold does not dissolve in hydrochloric acid.
Does hydrochloric acid dissolve gold"?
Yes, hydrochloric acid can dissolve gold.
Will hydrochloric acid dissolve gold?
Yes, hydrochloric acid can dissolve gold.
What solution will dissolves the metal gold?
Aqua regia is a solution that can dissolve gold. It is a mixture of nitric acid and hydrochloric acid that can react with and dissolve gold, forming a soluble gold chloride complex.
Will sulfuric acid dissolve gold?
No, sulfuric acid cannot dissolve gold. Aqua regia, a mixture of nitric acid and hydrochloric acid, is typically used to dissolve gold.
Does gold dissolve in hydrochloric acid?
Yes, gold does not dissolve in hydrochloric acid.
Does hydrochloric acid dissolve gold"?
Yes, hydrochloric acid can dissolve gold.
Will hydrochloric acid dissolve gold?
Yes, hydrochloric acid can dissolve gold.
What solution will dissolves the metal gold?
Aqua regia is a solution that can dissolve gold. It is a mixture of nitric acid and hydrochloric acid that can react with and dissolve gold, forming a soluble gold chloride complex.
Will sulfuric acid dissolve gold?
No, sulfuric acid cannot dissolve gold. Aqua regia, a mixture of nitric acid and hydrochloric acid, is typically used to dissolve gold.
Can aqua regia dissolve gold?
Yes, aqua regia can dissolve gold. Aqua regia is a mixture of nitric acid and hydrochloric acid that is able to dissolve gold and other noble metals.
How do you dissovle gold?
Aqua Regia will dissolve gold. Aqua Regia is a mixture of Nitric acid and Hydrochloric acid.
Which acid you need to use for gold test hydrochloric acid and sulfuric acid?
Hydrochloric acid is typically used for testing gold because it can help dissolve other metals that might be present along with the gold. Sulfuric acid, on the other hand, is not commonly used for testing gold and may not be as effective as hydrochloric acid.
What comes out of hydrochloric acid and gold?
When gold reacts with hydrochloric acid, it does not dissolve or react. Gold is a noble metal and is unreactive to most acids, including hydrochloric acid.
Does gold reacts with acids?
Gold does not react with most acids, including hydrochloric acid and sulfuric acid. However, aqua regia, a mixture of nitric acid and hydrochloric acid, can dissolve gold to form gold chloride. This property is often used in gold recovery and refining processes.
Will nitric acid dissolve other metals out of the gold?
Yes, nitric acid can dissolve other metals from gold through a process called aqua regia. This mixture of nitric acid and hydrochloric acid is particularly effective in dissolving a variety of metals, leaving behind the gold.
What mixture of acids is capable of dissolving gold?
Aqua regia, a mixture of nitric acid and hydrochloric acid, is capable of dissolving gold. The combination of these two acids creates a powerful solvent that can break down the gold's crystal lattice structure, allowing it to dissolve.
