Its +3 oxidation state is the most common, and can be obtained by dissolving its elemental form in hydrochloric acid or sulfuric acid, though it also comes in +4, +5, and +6 varieties. Trace amounts of this element replace aluminum in corundum to form rubies, and it is mixed with iron to form stainless steel alloys. FTP, what is this transition metal with atomic number 24 which is known for the bright colors of its compounds and complexes?
