because the arrangement of the oxygens in the crystal structure sets the energy difference between a molecular orbital energy level and its excited state to correspond to that wavelength of light. If you change the orientation of the oxygens, change the number of oxygens or change the ligands to something altogether different, the difference in molecular orbital energy levels will also change. The new energy difference will correspond to a new color.

Which industry uses vanadium pentoxide?
vanadium pentoxide is used as an in oxidation catalysts to produce chemicals like sulfuric acid, maleic anhydride, phthalic anhydride and others. it is also used in catalsyts for pollution control applications (DeNOx and DeSOx catalysts for removing nitrogen oxides and suflur dioxide from flue gases in power stations and industrial plants). Vanadium pentoxide is also used in ceramic frits as a fluxing agent and pigment as well as UV absorbing glasses. Vanadium pentoxide can be converted into ferrovaandium alloy for use in high strength low alloy steels, tool steels and high speed steels. it can also be converted into vanadium-aluminum alloys used in the production of titanium alloys for aerospace, industrial and recreational applications.
What is vanadium trioxide?
It is a compound in the form V2O3 with vanadium of an oxidation state of (III). It is derived from reduction of vanadium pentoxide V2O5. It is mostly used as a catalyst of various reactions. Personally I've produced it by reducing vanadium pentoxide in sulfuric acid, heating for 30mins then creating a basic solution using sodium carbonate.
Who are the global market leaders in vanadium?
In 1998 South Africa controlled 89 percent of the vanadium pentoxide market, China held a 6 percent market share, and Russia had 4 percent of the market.
Why is vanadium pentoxide preferred to platinized asbestos as a catalyst during catalytic oxidation of SO2?
Asbestos is avoided because his carcinogenic properties.
What materials are used in vanadium mining?
The main material used in vanadium mining is vanadium-rich magnetite ore. This ore contains high amounts of vanadium pentoxide (V2O5), which is the primary source of vanadium. Other minerals and compounds may be present in smaller quantities, but vanadium-rich magnetite is the primary material of interest.
What are the observations when you heat ammonium metavanadate in a nickel crucible?
When heated, ammonium metavanadate decomposes to form vanadium pentoxide and water vapor. The yellow color of the vanadium pentoxide is observed during the heating process. The water vapor produced can condense on the cooler parts of the crucible.

How much does vanadium cost?
The cost of vanadium can vary depending on factors such as purity, quantity, and market demand. As of September 2021, the price of vanadium pentoxide (V2O5) is around $9-10 per pound. However, prices can fluctuate due to changes in supply and demand, as well as geopolitical factors impacting the mining and production of vanadium. It is advisable to check current market prices for the most up-to-date information on vanadium costs.
What are the optimum conditions for synthesis of sulphuric acid by contact process?
pressure- 1.5 to 1.7atms temp -400 to 450 celcius catalyst must be vanadium pentoxide or platinised asbestos
Which Catalyst used in manufacture of sulphuric acid?
Vanadium pentoxide (V2O5) is commonly used as a catalyst in the manufacture of sulfuric acid by the contact process. It helps to speed up the reaction of sulfur dioxide with oxygen to produce sulfur trioxide, which is then converted into sulfuric acid.
