The oxidation state, sometimes referred to as oxidation number, describes the degree of oxidation (loss of electrons) of an atom in a chemical compound.Conceptually, the oxidation state, which may be positive, negative or zero, is the hypothetical charge that an atom would have if all bonds to atoms of different elements were 100% ionic, with no covalent component. Oxidation numbers are theoretical charges on individual atoms. In which reaction does the oxidation number of hydrogen change? Its oxidation number of oxygen that is -2, also remember that to see whether there is a redox reaction, u have to calculate the oxidation number of only the atom with variable oxidation number not of whole compound (the oxidation number of whole compound is always constant, usually 0). [Al] - 0(5H2O) -1(Cl^-) = 2+ hence this is an Al(III) cmplx. All Rights Reserved. 1. In almost all cases, oxygen atoms have oxidation numbers of -2.
