The oxidation number is usually numerically equal to the oxidation state and so the terms oxidation state and oxidation number are often used interchangeably. The sequential enthalpies , free energies , and entropies for the hydration reaction M(H2O)n-12+ + H2O = M(H2O)n2+ were determined in the gas phase for M = Mg, Ca, Sr, Ba. On the left side of the equation, barium and chlorine are present in their elemental form, and, by definition, both have oxidation state of 0. The book says the answer is -1. Barium typically displays a +II oxidation state in its compounds. Oxidation number is the charge left on the atom of interest, when all the bonding pairs of electrons are broken with the charge devolving to the most electronegative atom. Since the salt molecule needs to be neutral the two dihydrogen hypophosphite ions are single charged. For CuCO 3, it is made up of Cu 2+ and CO 3 2-ions. Thus, a reduction half-reaction can be written for the O 2 as it gains 4 electrons: In the compound sulfur dioxide (SO2), the oxidation number of oxygen is -2. 40, D‐01187 Dresden, Germany.
