| picric acid |
Picric acid is the common term for the chemical compound 2,4,6-trinitrophenol, also known as TNP; the material is a yellow crystalline solid. Like other highly nitrated compounds (eg. trinitrotoluene), picric acid is an explosive. When picric acid is dry, it is extremely sensitive to shock and friction, so laboratories that use it store it in bottles under a layer of water, rendering it safe. ...
