Can't do. Nitric acid would vaporize if added to molten gold.

To extract gold from an alloy using nitric acid, you can dissolve the alloy in nitric acid, which will selectively dissolve the base metals in the alloy, leaving behind the gold. Once the base metals are dissolved, you can precipitate the gold from the solution by adding a reducing agent, such as copper or ferrous sulfate, which will cause the gold to drop out of the solution as a solid. Finally, the solid gold can be filtered out and further refined to obtain pure gold.

The name of HNO3 is?
The chemical name of HNO3 is nitric acid
Why sodium extract is boiled with concentrated nitric acid before testing halogens?
Boiling the sodium extract with concentrated nitric acid helps to oxidize any halides present to their respective halogens. This reaction helps to release the halogens from the sample so they can be detected more easily in subsequent tests.
Can nitric acid melt brass?
Yes, nitric acid can dissolve brass by reacting with the copper content in the alloy. However, it typically does not melt brass in the literal sense of melting from solid to liquid. Instead, it corrodes and breaks down the brass over time.
Why lead nitrate is not used in preparing nitric acid?
Lead nitrate is not used in preparing nitric acid because it is not a source of nitric acid; it is a salt of lead. Nitric acid is typically produced by the oxidation of ammonia using a catalyst, or by the reaction of nitrogen dioxide with water. Lead nitrate is toxic and can be hazardous to handle, so it is not used in the production of nitric acid.
What is the periodic name for nitric acid?
The systematic name for nitric acid is hydrogen nitrate.
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.
The name of HNO3 is?
The chemical name of HNO3 is nitric acid
What is the slovent and the solute of a 10-karat bracelet?
The answer depends on what other metals are in the alloy.
Can nitric acid melt brass?
Yes, nitric acid can dissolve brass by reacting with the copper content in the alloy. However, it typically does not melt brass in the literal sense of melting from solid to liquid. Instead, it corrodes and breaks down the brass over time.
Nitric acid reacts with nitric acid?
No, it does not
In what form does nitric acid exist?
Nitric acid typically exists in its liquid form since it is a highly corrosive and strong acid. It can also be found in its solid form as anhydrous crystals, and in its gaseous form as nitrogen dioxide in equilibrium with the liquid.
Is nitric acid a heterogeneous?
nitric acid is heterogeneous.
What is compound of H2NO3?
The composition of hno3 is HNO3 , with one hydrogen atom, one nitrogen atom, and three oxygen atoms. The name of this molecule is nitric acid. Refer to the related link for a structural formula of nitric acid.
What does gold plus nitric acid yield to?
Gold reacts with nitric acid to form gold(III) nitrate, nitrogen dioxide gas, and water. This reaction is commonly used in the purification and analysis of gold.
How many molecules of nitric acid are in 300 g of nitric acid?
The number of nitric acid molecules is 28,6723.10e23.
What is the periodic name for nitric acid?
The systematic name for nitric acid is hydrogen nitrate.
What is the source of nitric acid?
Nitric acid is typically produced by the oxidation of ammonia with air in the presence of a catalyst at high temperatures. This process creates nitrogen dioxide, which is then dissolved in water to form nitric acid. Additionally, nitric acid can also be produced by the reaction of nitrogen oxides with water.
