The percentage of nitrogen in the picric acid is 18,34 %.
The percentage of nitrogen in the picric acid is 18,34 %.
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
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.
React aniline with HCl/NaNO2 (diazotisation) followed by reaction with KOH to give phenol. Nitration of phenol with fuming nitric acid gives picric acid (or trinitrophenol).
In microbiology, microbial pathology and taxonomy:A variety of phenotypic tests can be used to identify and distinguish Mycobacteria strains and species from each other, one of them is thePicrate tolerance test: Ability to grow on Sauton agar containing picric acid (0.2% w/v) after 3 weeks

i truelywanna know why was picric acid used to treat burns?

Hydrochoric acid is more acidic than Picric acid.Added: Ka(Picric acid) = 0.38, Ka(HCl) >>1
for three electron withdrawing nitro groups, picric acid is highly acidic
React benzene with conc. H2SO4 and then with conc. HNO3. The resultant would be picric 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'.
Picric acid
Picric acid is a fixative (for example is found in Bouin's) but can be found in picrosirius red (is required for the sirius red stain to selectively bind collagen).
kaboom!
