Chromium trioxide (also known as chromium(VI) oxide or chromic anhydride) is an inorganic compound with the formula CrO3. It is the acidic anhydride of chromic acid, and is sometimes marketed under the same name. This compound is a dark-purple solid under anhydrous conditions, bright orange when wet and which dissolves in water concomitant with hydrolysis. Millions of kilograms are produced annually, mainly for electroplating. Chromium trioxide is a powerful oxidi… WebFeb 4, 2024 · PCC was invented as a workaround to this problem: it works as a reactant in anhydrous enviroment, hence stopping the reaction at the aldheyde stage. An alternative way to see PCC is to follow its preparation: if you add C r O X 3, H C l and pyridine, PCC is formed. If you add C r O X 3, acid and water, chromic acid is formed. derrick henry wallpaper hd
