Which substance does phosphorus have a +3 oxidation state? satishkumar2728 satishkumar2728 Answer: 2OH Bonds . On the other hand, let Cl 2 be taken in excess, then initially formed PCl 3 reacts further to form PCl 5 in which P has +5 oxidation state. It will attack the terminal positions, so we get four additional oxygens and a final $\ce{P4O10}$ . Find the oxidation number of S in K2S2O8. P 2 O 5 (or P 4 O 10) can be prepared by burning elemental P 4 (tetra-phosphorus) in an environment containing a sufficient amount of oxygen. Compare the oxidation number of the element on the reactant side and on the product side. 1 answer. Alkali metals exhibit only an oxidation state of +1 in compounds. d) The oxidation states vary in a period while remains same in a group. Alkaline earth metals exhibit only an oxidation state of +2 in compounds. What is the oxidation number on N in Li3N? The H 3 PO 2 is a neutral molecule, so the overall charge is zero (0).. There's nothing surprising about the normal Group oxidation state of +4. Therefore, the oxidation number of sulfur in the compound is -2, and the sum of the oxidation numbers is 0. What is the oxidation state of P in P 4? Answer: The oxidation number of chromium in the given compound is +6 Explanation: Oxidation number is defined as the number which is assigned to the element when it gains or loose electrons.If the element gains electron, it will attain a negative oxidation state and if the element looses electrons, it will attain a positive oxidation state. 6. Therefore, to maintain the -2 charge of the molecule, Cr will have to be +6.
