In 1825, Leopold Gmelin extracted croconic acid C5 H2 O5 and potassium croconate dihydrate K2 C5 O5 ยท2H2 O from the reaction mixture obtained by heating potassium carbonate with carbon. He observed the metal first becoming silver-colored, then gray, and finally deep black. When the absorption of carbon monoxide was complete, a vigorous reaction suddenly turned the black material into a stable product with the appearance of . . .
