Chlorine, bromine, and iodine usually have an oxidation number of â1, unless theyâre in combination with an oxygen or fluorine. oxidation number of of phosphorus in orthophosphoric acid hypophosphorous acid and phosphorus acid Loading... Autoplay When autoplay is enabled, â¦ Phosphorus also shows +1 and + 4 oxidation states in some oxo acids. What is the oxidation no. Answer Save. Answer Save. Join. We can find oxidation numbers of sulfur and hydrogen in H 2 S by several methods.. So, if hydrogen has an oxidation number of +1 in a water molecule, then there are two atoms with that number, and the total for hydrogen is +2. O is always -2 so the O's have a -8 charge. 1 decade ago. +1 C. +3 D. +5 E. â2 Its oxidation number is â 1. 0 0. What is the time signature of the song Atin Cu Pung Singsing? What this tells you is that the oxidation number of P in phosphorus acid must be +3 or +4, while the value for phosphoric acid must be +5 or +6. Since phosphorus is a member of group 5A, it has 5 electrons in its valence shell. Oxygen is -2 (by assignment) and As is +5 The convention is to assign -2 to oxygen when it appears in any compound (except for H_2O_2 where it is -1). if O is -2 and hydrogen +1 then phosphorus is +5. Favourite answer. I have also found evidence that it may be -3, +3. 1 decade ago. As in the given ion, hydrogen is bonded with non-metal oxygen and there are three hydrogen atom, the oxidation number of hydrogen atom is 3. Ask Question + 100. +2 Oxidation number of hydrogen =+1 Oxidation number of oxygen = -2 Let oxidation number of phosphorous be a.
