Chromium trioxide
Inorganic Compound
Chromium trioxide is an inorganic compound with the formula CrO&©|8323;. It is theacidic anhydride of chromic acid, and is sometimes marketed under thesame name. This compound is a dark-purple solid under anhydrousconditions, bright orange when wet and which dissolves in waterconcomitant with hydrolysis. Millions of kilograms are produced annually, mainly for electroplating. Chromium trioxide is a powerful oxidiser and acarcinogen.
&©|8226; Ionic compound (Chromium is a metal)
&©|8226; Valence of O (O must form an octet): 6
&©|8226; Valence of Cr: 6
&©|8226; Total valence electrons: 24
&©|8226; Molar mass: 99.99 g/mol
&©|8226; A major use of chromium trioxide has been in chromium plating, particularly in the production of automobiles. Uses in other metal-finishing operations include aluminium anodizing, particularly on military aircraft; chemical conversion coatings, which provide both decoration and corrosion protection; and the production of phosphate films on galvanized iron or steel. Other uses of chromium trioxide are as a wood preservative, as a corrosion inhibitor for ferrous alloys in recirculating water systems, as an oxidant in organic synthesis and in catalyst manufacture. Small amounts are used to modify the properties of basic magnesite refractories.
