Pi"cric, a. Etym: [Gr. (Chem.)
Definition: Pertaining to, or designating, a strong organic acid (called
picric acid), intensely bitter.
Note: Picric acid is obtained by treating phenol with strong nitric
acid, as a brilliant yellow crystalline substance, C6H2(NO2)3.OH. It
is used in dyeing silk and wool, and also in the manufacture of
explosives, as it is very unstable when heated. Called also
trinitrophenol, and formerly carbazotic acid.
