Chromium(III) oxide is amphoteric. Although insoluble in water, it reacts with acid to produce salts of hydrated chromium ions such as [Cr(H 2O) 6] . It is also attacked by concentrated alkali to yield salts of [Cr(OH) 6] . When heated with finely divided carbon or aluminium, it is reduced to chromium metal: Cr 2O 3 + 2 Al → 2 Cr + Al 2O 3 WebExplain why chromium is placed in the d block in the Periodic Table. ... Explain, in terms of structure and bonding, why sulfur trioxide has a higher melting point than sulfur dioxide. Sulfur trioxide is a larger molecule than sulfur dioxide so the van der Waals' forces between the molecules are stronger.
WebIDENTIFICATION AND USE: Chromic trioxide is a brown solid. It is used Chromium plating, copper stripping, aluminum anodizing, corrosion inhibitor, photography, purifying oil and acetylene, hardening microscopical preparations, oxidizing agent in organic chemistry. It is also has been used as a veterinary medication.
Chromium trioxide decomposes above 197 °C, liberating oxygen and eventually giving Cr 2 O 3 : 4 CrO 3 → 2 Cr 2 O 3 + 3 O 2. It is used in organic synthesis as an oxidant, often as a solution in acetic acid, [8] or acetone in the case of the Jones oxidation.
