Encyclopedia Article for picric-acid

picric acid

pale yellow, odourless crystalline solid that has been used as a military explosive, as a yellow dye, and as an antiseptic. Picric acid (from Greek pikros, "bitter") was so named by the 19th-century French chemist Jean-Baptiste-Andre Dumas because of the extremely bitter taste of its yellow aqueous solution. Percussion or rapid heating can cause it (or its salts with heavy metals, such as copper, silver, or lead) to explode.
