In Na2SO4……..Na and O molecule doesnt have variable oxidation state or no. Get answers by asking now. The oxidation number of Na in Na2O is +1 because Na is in group IA. Water as such is a neutral stable molecule. If it is possible to oxidize any of the elements in a given compound, further oxidation by oxygen can occur. Oxidation state in metals. By definition, the oxidation state of an atom is the charge that atom would carry if the compound were purely ionic. For example, hydrogen sulfide, H 2 S, contains sulfur with an oxidation state of 2−. Matter can often change from one physical state to another in a process called a physical change.

Many compounds with luster and electrical conductivity maintain a simple stoichiometric formula; such as the golden TiO, blue-black RuO 2 or coppery ReO 3, all of obvious oxidation state.Ultimately, however, the assignment of the free metallic electrons to one of the bonded atoms has its limits and leads to unusual oxidation states. Previous question Next question Get more help from Chegg. The total concentration of chromium at the liquid/chromia interface is imposed by the oxygen pressure. Oxidation states provide a compromise between a powerful model of oxidation-reduction reactions based on the assumption that these compounds contain ions and our knowledge that the true charge on the ions in these compounds is not as large as this model predicts. Remember in the elemental state atoms have zero oxidation numbers. Under these conditions the catalytic formation of water can also be monitored [9]. C oxidation state of all neutral atoms is 0.
