Is there an alternative for nitric acid using aqua regia?
Yes, instead of aqua regia you can use the mixture of thionyl chloride (SOCl2) and the organic solvent pyridine.
Which metal does not react with HCl?
Gold does not - it needs aqua regia
How much quantity need of aqua regia to dissolve 5000gms of gold?
A cup of aqua regia
Chemical composition for Aqua regia?
aqua regia is a solution of nitric acid+hydrochloric acid. ratio is 3:1.
Does aqua-regia etch silicon nitride?
no
What happens when a metal is dipped in aqua regia?
Formation of the metal chloride and hydrogen gas, depending on the metal of course. Not all metals will react.
Which of material is resistant to boiling aqua regia?
Silver can be resistant to boiling aqua regia due to formation of silver chloride.
Why aqua regia don't react with silver?
silver chloride forms, which is insoluble in aqua regia, HCl, or HNO3. silver chloride is soluble in ammonium solutions but this can become very dangerous, as fulminate forms and can detonate when dried, acidifying them with HCl to precipitate the silver and form ammonium chloride solution is a safe way to handle them. insolubility of silver chloride in aqua regia is one reason karat gold is inquatered, and parted in nitric before dissolving gold in aqua regia, the insoluble silver chloride will crust over the gold (from silver in the karat gold), and aqua regia cannot dissolve the gold with an layer of silver chloride protecting the gold from the acids. some small amounts of silver chloride is soluble in aqua regia, remember soluble, or insoluble are relative terms, and can be affected by temperature, PH and so on. metal refiner Richard B.

What is the formula for aqua regia?
There is no single "chemical equation for aqua regia". Aqua regia is a mixture of concentrated nitric and sulfuric acids, which is capable of many reactions. The characteristic that gave aqua regia its name is its ability to dissolve gold, but dissolution is usually not considered a chemical reaction
What is the solute of aqua-regia?
Aqua regia ia mixture of HCl and HNO3. The expression solute/solvent in this case is not adequate.
