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.
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 is mucic acid test?
The mucic acid test is a chemical test used to detect the presence of mucic acid in a substance. It involves the use of reagents that react with mucic acid to produce a characteristic color change. This test is commonly used in the identification of certain carbohydrates.
What is the purpose of a purity test?
Purity tests are used to determine the extent to which a particular substance is what is claimed. A classic purity test for gold is nitric acid; if the item being examined reacts to the acid it is not gold, or at least not pure gold.
What acid will eat copper but not gold?
Nitric acid can dissolve copper but not gold. Gold is resistant to most acids, including nitric acid, which is commonly used to dissolve copper.
What acid do you use for the acid test?
For the acid test to determine the authenticity of gold, you typically use nitric acid. Nitric acid is used to test the purity of gold based on the reaction it produces with the metal.
What chemical is used to test gold?
A commonly used chemical for testing gold is nitric acid. Gold does not react with nitric acid, allowing it to be used to determine the purity of gold based on the reaction with other metals present in the sample.
What reagent used to test heller's test in protein precipitation?
Heller's test uses strong acids, such as nitric acid or trichloroacetic acid, to precipitate proteins. The protein precipitation occurs due to denaturation of the proteins in the presence of the acid, leading to their insolubility and precipitation.
Can concentrated nitric acid be used in flame test instead of concentrated hydrochloric acid?

What is the best acid to test for gold?
Nitric acid is commonly used to test for the presence of gold. Gold does not react with nitric acid, distinguishing it from other metals that may be present in a sample. However, please note that handling acids requires proper safety precautions, and it's essential to conduct such tests in a controlled environment.
Does a sapphire have a acid test?
No, sapphires do not pass the acid test. The acid test is a method used to distinguish between real gold and other materials based on their reaction to nitric acid, but sapphires are unaffected by acid.
Is nitric acid the same as sulfuric acid?
nitric acid be used insted of hypophrosphous acid
Example two acids used in the laboratory?
Nitric acid, hydrochloric acid.
Does gold react with nitric acid?
Yes, gold does react with nitric acid to form gold nitrate. This reaction is often used to test the purity of gold because impure gold will react differently.
Is nitric acid a acid or alkaline?
Nitric acid is an acid. It is a strong mineral acid commonly used in industries such as manufacturing and metal processing.
Are fertilisers nitric acid?
No. Nitric acid is used to produce the ammonium nitrate which goes into fertilizers.
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.
