Why direct nitration is used in picric acid?
in picric acid we cannot used direct nitration because of the phenol is very sensitive in oxidation of nitrate, to overcome this problem, we used a sulfuric acid added to phenol before the nitric acid. the reaction between NO2 and SO2 are reversible so the sulphate exchange with nitrate becoming tri nitrophenol
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.
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'.
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.
What Aromatic Hydrocarbon has been prepared in the reaction between Sulfuric Acid and Benzene?
Benzene sulfonic acid is produced in the reaction between sulfuric acid and benzene. This reaction involves the substitution of a hydrogen atom on the benzene ring with a sulfonic acid group (SO3H).

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 the picric acid is vary strong?
There are three deactivating -NO2 groups attached to benzene ring.They reduce electron density of benzene ring very much.So electrons of Oxgen in -OH group attract to benzene ring.Then the negativity of Oxygen reduces.So it is very much easy to break O-H bond and emmit H+.
What is another term for Ferrous Nitrite?
Picric acid
Why are picric acid used in the treatment of burns?
Picric acid reduced pain and infection and allowed the formation of a scab under which healing took place.Using a one percent solution of picric acid, the wound was cleansed and then all blisters were pricked to release the serum (blister fluid), taking care not to remove the blister itself. The burn was covered with sterilized gauze soaked in the picric acid solution. The gauze was padded with cotton wool and held in place with a light bandage. After three or four days, the dressing was soaked off and the wound redressed.
what is picramic acid?
Picramic acid is an organic compound that is derived from picric acid, which is a nitro compound. It has the chemical formula C6H4N2O3 and is formed by the reduction of picric acid. Picramic acid is primarily used in the synthesis of dyes and other organic compounds.
