How to prepare nitrate test solution using diphenylamine in sulphuric acid?
To prepare a nitrate test solution using diphenylamine in sulfuric acid, you can mix diphenylamine with concentrated sulfuric acid in a specific ratio. Typically, a 0.1% diphenylamine solution in concentrated sulfuric acid is used for nitrate testing. Follow safety precautions when working with concentrated sulfuric acid as it is corrosive.
What happens to glucose in the phenol sulfuric acid test?
In the phenol sulfuric acid test, glucose reacts with phenol and sulfuric acid to form a colored product. The color change is due to the formation of furfural, which reacts with the sulfuric acid to produce a colored compound. This color change is used to detect the presence of glucose in a sample.
What is difference between sulphated ash and residue on ignition?
Sulphated ash is the amount of inorganic residue left when a sample is ignited after treatment with sulfuric acid. On the other hand, residue on ignition is the amount of material left behind when a sample is ignited without any prior treatment. Sulphated ash is typically used for organic materials, while residue on ignition is often used for inorganic materials.
Why can't sulfuric acid be used instead of hydrochloric acid in the barium chloride test?
Sulfuric acid cannot be used in place of hydrochloric acid in the barium chloride test because sulfuric acid would react with barium chloride to form insoluble barium sulfate. This would interfere with the precipitation reaction used to detect the presence of sulfates in the sample. Hydrochloric acid is preferred because it does not interfere with this reaction.
What was the liquid used in the solubility test with Twinkies?

Why can't sulfuric acid be used instead of hydrochloric acid in sulphate test?
Using sulfuric acid in place of hydrochloric acid for a sulfate test can produce inaccurate results due to the formation of insoluble precipitates with some sulfates. This can interfere with the detection of sulfate ions in the test solution. Hydrochloric acid is preferred as it reduces the likelihood of forming these precipitates, ensuring a more reliable sulfate test.
Which acid you need to use for gold test hydrochloric acid and sulfuric acid?
Hydrochloric acid is typically used for testing gold because it can help dissolve other metals that might be present along with the gold. Sulfuric acid, on the other hand, is not commonly used for testing gold and may not be as effective as hydrochloric acid.
Is h2so4 a acid or base?

What is the most used acid in the world?
Sulfuric Acid
What acid is used in car batteries?
Sulfuric acid
Have you ever used Zep sulfuric acid drain cleaner and what was your experience with it?
I have not personally used Zep sulfuric acid drain cleaner.
What will happened if Hydrochloric acid is used instead of sulfuric acid in molisch test?
Using hydrochloric acid instead of sulfuric acid in the Molisch test would yield a different result. Hydrochloric acid does not have the same dehydrating properties as sulfuric acid, so it would not lead to the formation of a purple ring with carbohydrates. The Molisch test relies on the dehydrating ability of sulfuric acid to break down carbohydrates into simpler compounds, which then react with alpha-naphthol to produce the purple ring.
