Lv 5. +2 and +3 for Fe in Fe3O4. The color depends on the viewing angle: by reflected light the crystals appear dark green, but by transmitted light they appear purple-red. Oxidation number (also called oxidation state) is a measure of the degree of oxidation of an atom in a substance (see: Rules for assigning oxidation numbers). But we have to know that the HCl is this reaction is creating the acidic environment for the reaction. [citation needed] It is less powerful than aluminium chloride, but in some cases this mildness leads to higher yields, for example in the alkylation of benzene: The ferric chloride test is a traditional colorimetric test for phenols, which uses a 1% iron(III) chloride solution that has been neutralised with sodium hydroxide until a slight precipitate of FeO(OH) is formed.
