We know, the sum of oxidation numbers of all entities is equal to total charge on compound. Hence, oxidation number of As in H3AsO4 is +5.Click to see full answer. Also question is, what is the oxidation state of arsenic in H3AsO3?+5Similarly, what is the oxidation state of each element in so2 − 4? 10. The sum of the oxidation numbers in a polyatomic ion is equal to the charge on the ion. The oxidation number of the sulfur atom in the SO42- ion must be +6, for example, because the sum of the oxidation numbers of the atoms in this ion must equal -2. what is the oxidation number for arsenic? Oxidation number is the property of an element in a chemical form. In AsH3, arsenic has oxidation number -3, but in AsF3, arsenic has oxidation number +3. In H3AsO4 (arsenic acid), arsenic has oxidation number +5. Those are the most common oxidation numbers for arsenic.What is the oxidation state of Fe?Explanation: However, the oxidation number of Fe in its compounds can take different values. The most common oxidation numbers of Fe are +2, as in FeCl2 , and +3, as in FeCl3 .
