Picric acid is a fairly strong acid. Most phenols are very weak acids, although they do react with strong bases. Since picric acid (2,4,6-trinitrophenol) has three strong electron-withdrawing nitro groups on its ring, its anion is more stable than most phenolates, and that makes it a much stronger acid.

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?
Hydrochoric acid is more acidic than Picric acid.Added: Ka(Picric acid) = 0.38, Ka(HCl) >>1
How picric acid is strong acid?

How will you prepare picric acid from benzene?
React benzene with conc. H2SO4 and then with conc. HNO3. The resultant would be picric acid
Is picric acid a dye or fixative?
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).

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.

Picric acid
How to convert aniline to picric acid?
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).
