Hydrogen sulfide is then added to the resulting solution, which turns red, yielding sulfur and red crystals. These are the ammonium salts of picramic acid, from which it can be extracted using acetic acid.〔http://www.jbc.org/content/35/3/565.full.pdf〕 Picramic acid is explosive and very toxic. It has a bitter taste.〔http://chemicalland21.com/specialtychem/perchem/PICRAMIC%20ACID.htm〕 == References == 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Picramic acid」の詳細全文を読む スポンサード リンク
