Fulminic acid

Fulminic acid is a chemical compound with a molecular formula HCNO. Its silver salt was discovered in 1798 by Luigi Valentino Brugnatelli who found that if silver was dissolved in nitric acid and the solution added to spirits of wine, a white, highly explosive powder was obtained. In 1800 Edward Charles Howard also created silver salt and was later investigated in 1824 by Justus von Liebig. Howard also created mercuric salt in 1799, who substituted mercury for silver in Brugnatelli’s process. Wikipedia
