How will you prepare picric acid from benzene?
Picric acid can be prepared from benzene by first nitration to form nitrobenzene, followed by further nitration and subsequent treatment with a nitric/sulfuric acid mixture to yield picric acid. The process involves multiple steps and careful control of reaction conditions to avoid explosive hazards. It is important to handle picric acid with caution due to its potentially explosive nature.
In real picric acid is not acid..then why it called acid?
Picric acid is acidic, as it has a fairly acidic phenolic proton. However, picric acid is not a carboxylic acid. Nevertheless, it is still called 'acid' because of its acidic proton, just as phenol was once called 'carbolic acid'.
Which is more acidic hydrochloric acid or picric acid?
Hydrochloric acid is more acidic than picric acid. Hydrochloric acid fully dissociates in solution to release hydrogen ions, resulting in a lower pH compared to picric acid, which is a weaker acid that does not fully dissociate in solution.
What happens when phenol reacts with concentrated HNO3 plus H2SO4?
When phenol reacts with concentrated nitric acid (HNO3) in the presence of sulfuric acid (H2SO4), a mixture of products is formed, including picric acid (2,4,6-trinitrophenol) and water. This reaction is known as nitration of phenol and is used to synthesize picric acid, which is a yellow, explosive compound.
What happens if you mix Picric acid and Sodium hydroxide?
Mixing picric acid with sodium hydroxide can result in a potentially dangerous reaction. It can form highly explosive picrate salts which are shock-sensitive. Extreme caution should be taken when handling these substances and they should never be mixed together.

What is picric acid and it's use picric acid?
Picric acid, or 2,4,6-trinitrophenol, is a yellow crystalline compound that is both a powerful explosive and a chemical reagent. Historically, it was used as an explosive in military applications and as a precursor for the production of dyes and pharmaceuticals. Uses of Picric Acid: 1. Explosives: Primarily used in munitions during World War I and II, picric acid is a high explosive, often used in shells and bombs. 2. Chemical Reagent: In laboratories, it serves as a reagent in organic synthesis, particularly in the preparation of nitro compounds. 3. Biological Staining: It is used in histology and microscopy for staining tissues and cells. 4. Pharmaceuticals: While less common today, picric acid has been investigated for potential uses in medicine, such as in the treatment of certain conditions. 5. Research: It is utilized in various research applications, particularly in studying the properties of nitrogen-containing compounds. Despite its applications, picric acid is highly hazardous, both as an explosive and due to its toxic nature, necessitating careful handling and storage.
What happens when picric acid reacts with sodium bicarbonate?
When picric acid reacts with sodium bicarbonate, it produces carbon dioxide gas, water, and sodium picrate. The carbon dioxide gas can be observed as bubbling or effervescence during the reaction. Sodium picrate is a less explosive compound compared to picric acid.
What is IUPAC name of picric acid?
The IUPAC name for picric acid is 2,4,6 trinitrophenol
What is the picricacid formual?
picric acid (or 2,4,6-trinitrophenol) is more acidic than benzoic acid The pKa or picric acid is 0.3 and that of benzoic acid is 4.2
Which is more acidic hydrochloric acid or picric acid?
Hydrochloric acid is more acidic than picric acid. Hydrochloric acid fully dissociates in solution to release hydrogen ions, resulting in a lower pH compared to picric acid, which is a weaker acid that does not fully dissociate in solution.
What is the mass percent of nitrogen in the dyeing agent picric acid (C6H3N3O7)?
The percentage of nitrogen in the picric acid is 18,34 %.

Why was picric used in treating burns?
i truelywanna know why was picric acid used to treat burns?
How picric acid is strong acid?
Picric acid is a strong acid because it readily donates a proton (H+) in solution, making it highly reactive with bases. It has a low pKa value, indicating that it dissociates almost completely in water to release hydrogen ions. This property gives picric acid its characteristic acidic behavior.
