What is a mixture of concentrated nitric acid and concentrated hydrochloric acid is called?

∙ 13y ago
This mixture is called Aqua regia (Latin: royal water) or aqua regis, which is a highly corrosive, fuming yellow or red solution, also called nitro-hydrochloric acid.
The mixture is formed by freshly mixing concentrated nitric acid (12M) and concentrated hydrochloric acid (18M), usually in a molar ratio of 1:3 (volume ratio 1:2) respectively.
Only this mixture is capable of dissolving gold (Au).
Chemical reaction equation (Be aware of toxic fumes !):
Au(s) + NO3-(aq) + 4 H+(aq) → Au3+(aq) + NO(g) + 2 H2O(l)

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.
What can desolve gold?
Aqua regia, a 1:3 mixture of concentrated nitric and hydrochloric acids, can dissolve gold, platinum, and other inert metals.
What mixture of acids is capable of dissolving gold?
Aqua regia:a mixture of concentrated HCL(hydrochloric acid)&conc. HNO3(nitric acid) in ratio of 3:1 ,can dissolve gold.
Does gold reacts with acids?
Normally it doesn't but it will react with a mixture of nitric and hydrochloric acids called aqua regia.
How do you separate gold from a zinc-gold mixture?
Gold when put in aqua regia dissolves. Aqua regia is obtained by mixing concentrated nitric acid and concentrated hydrochloric acid.Once the gold is dissolved the metals are participated out by adding salts ( not table salt) to the mixture.

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.

Can concentrated nitric acid be used in flame test instead of concentrated hydrochloric acid?
Cleaning of the test wire (platinum or nickel-chromium alloy) may by realized with nitric acid or hydrochloric acid.Rinsing is made with demineralized water.
Is silver completely non-reactive?
No. Silver will react with nitric acid and with aqua regia, a mixture of nitric and hydrochloric acid.
Carbon react with dilute hydrochloric acid?
Carbon don't react with acids, except concentrated Nitric acid. Concentrated nitric acid reacts with carbon to produce Water, Carbon dioxide, and Nitrogen dioxide.
What metals don't react with hydrochloric acid?
Gold and platinum. 'Aqua regia' is a mixture of trhe acids, hydrochloric acid and nitric acid. This mixture will react with these metals.
What is the purpose of aqua regia?
It is used to purify royal metals like gold.
Aquaregia is a mixture of?
Aqua regia refers to the mixture of hydrochloric acid and nitric acid in a ration of 4:1 or 3:1.
