WebThe oxidation states of iron, however, differ. Atoms of iron do not form the + 8 oxidation state corresponding to the loss of all the electrons in the 3d and 4s orbitals. This is in contrast to the adjacent element manganese that can lose all its 3d and 4s electrons to form the + 7 oxidation state. WebAug 21, 2024 · In the case of titanium, the reducing agent is either sodium or magnesium. Both of these would, of course, first have to be extracted from their ores by expensive processes. The titanium is produced by reacting titanium (IV) chloride, TiCl 4 - NOT the oxide - with either sodium or magnesium.
