Nitric acid (1 part by volume) mixed with conc.hydrochloric acid (3 parts by volume) produces a mixture called aqua regia.
HNO3 + 3HCl → NOCl + 2H2O + 2[Cl]
Aqua regia contains nascent chlorine and reacts with noble metals such as gold and platinum to produce chlorides.
Pt + 4[Cl] → PtCl4
Au +3[Cl] → AuCl3.

Will Aqua regia dissolve quartz rock to recover gold?
Aqua regia will dissolve gold. It will not dissolve quartz rock.
Does aqua regia dissolve diamond?
No. Aqua regia is used to dissolve noble metals: gold and platinum. It does not affect diamond.
Does gold dissolves in acid other than aqua regia?
Gold is generally resistant to most acids due to its low reactivity. However, it can dissolve in a few specific acids, such as a mixture of hydrochloric acid and nitric acid (aqua regia), which is the most well-known solvent for gold. Other than aqua regia, gold can also dissolve in certain complexing agents like cyanide, but this is not typical of traditional acids. In general, gold does not dissolve in simple acids like hydrochloric or sulfuric acid.
What is the purpose of aqua regia?
Aqua regia is a highly corrosive mixture of nitric acid and hydrochloric acid. Its purpose is to dissolve noble metals like gold, platinum, and palladium, which are resistant to other acids. Aqua regia is commonly used in the purification and extraction of these metals.
Aqua regia is the reaction endo or exo?
The reaction of aqua regia is exothermic because it releases heat when the acids interact with metals, causing a very strong and aggressive reaction that can dissolve gold and platinum.
Will Aqua regia dissolve quartz rock to recover gold?
Aqua regia will dissolve gold. It will not dissolve quartz rock.
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.
Does aqua regia dissolve diamond?
No. Aqua regia is used to dissolve noble metals: gold and platinum. It does not affect diamond.
How much quantity need of aqua regia to dissolve 5000gms of gold?
To dissolve 5000g of gold, you would need approximately 1 liter of aqua regia, which is a 3:1 mixture of hydrochloric acid to nitric acid. It's important to handle aqua regia with caution as it is a highly corrosive and reactive mixture.
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.
What is the uses of aqua-regia?
The main purpose of aqua-regia is to dissolve gold in it and it was first prepared by a Muslim scientist known as the father of the chemistry Jabar-Bin-Hayain :-)
Will mylar dissolve in aqua regia acid solution?
No, mylar is a type of polyester film that is resistant to most chemicals, including aqua regia. Aqua regia is a highly corrosive mixture of nitric acid and hydrochloric acid commonly used to dissolve noble metals like gold and platinum, but it will not dissolve mylar.
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.
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.
