WebIn all these examples, the total oxidation state of the molecule adds up to 0. On top of that, there is a general trend that O has an OS (Oxidation State) of -2 (usually) and H has an OS of +1 (again, usually). From that, we can calculate the unknown OS of C which tends to vary in these molecules. WebThey are said to have variable oxidation states Because of this, Roman numerals are used to indicate the oxidation state on the metal ion For example, the metal sodium (Na) will only form Na + ions (no Roman numerals are needed, as the ion formed by Na will always have an oxidation state of +1)
