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.
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 pH of tannic acid?
Tannic acid is a weak acid that can vary in pH depending on its concentration and the solvent it is dissolved in. Generally, tannic acid has a pH around 2-3 when dissolved in water.
What kind of acid is in tea?
Tea contains tannic acid, which gives it a slightly bitter flavor. Tannic acid is a type of polyphenol that can also contribute to the astringency of tea.
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'.
Why picric acid and tannic acids are used in the treatment of burns?
Picric Acid: 1. In the First World War the treatment of burns consisted in the application of various antiseptic dressings. Picric acid in a 1 per cent aqueous solution was commonly used. 2. The treatment by picric acid carried with it some danger of absorption when used over large raw surfaces, but it was generally a very satisfactory form of treatment. 3. It controled pain and rapidly promoted healing. Tannic acid: 1. The use of tannic acid was a distinct advance in the treatment of cutaneous burns and found the care of patients relatively simple. 2. Beneficial effects: rapid alleviation of pain, lessened infection, reduced local loss of body fluids, prosperous epithelization, relative absence of contractures, and diminished scar-tissue formation. 3. Most important of all, good survival statistics were reported in several studies. In a group of 114 patients treated with tannic acid, Beekman observed a mortality rate of 14.9 percent, which was considerably lower than the death rate of 27.8 percent in the 320 patients treated otherwise. He also showed that the number of patients dying from the second to the tenth day, the period of toxemia, was strongly decreased in the tannic acid-treated group.
Why was picric used in treating burns?

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.
