Why don't libraries smell like bookstores? asked Apr 4, 2019 in Redox reactions and electrochemistry by Simrank ( 72.0k points) Generally, it is clear that there are at least one P=O bond and one P–OH bond in these acids. P–P or P–H bonds are also present besides the P=O bonds and P–OH bonds in oxoacids of phosphorus. The acid strength is also explained by the oxidation number of central atom ( here P ) H3PO2 - +1. The Oxidation Number of P in H3PO2 is + 1. X = -1 -2 +4. P=6-3. Let us consider it as x. P shows +1 in this acid. When it is bonded to Fluorine (F) it has an oxidation number of +1. Indicate the oxidation number of phosphorus in each of the following acids: (a) HPO3 (b) H3PO2 (c) H3PO3 (d) H3PO4 (e) H4P2O7 (f | SolutionInn Phosphorus also shows +1 and + 4 oxidation states in some oxo acids. +3 Phophite (PO_3^(3-)) has a charge of -3, so I'm going to guess you meant to ask what the oxidation state of P was in H_3PO_3 In H_3PO_3 the oxygens will always have a -2 charge and hydrogen is +1. ON of H is 1 , ON of O is -2 , Lets take the ON of P is X. The Oxidation Number of Hydrogen (H) is + 1. =3. The oxidation number for phosphorus is +3: four covalent bonds with oxygen atoms yield +4 and the central charge yields -1. oxidation state of hydrogen is +1. The oxidation number of a free element is always 0. To confirm, substitute the value obtained in the formula, the answer should be zero as the charge on the molecule is zero. The Oxidation Number of Oxygen (O) is -2. of P is + 5, in hypophosphorous acid $\ce{(H3PO2)}$ it is + 1 while in metaphosphoric acid $\ce{(HPO3)}$, it is + 5. With more number of 0 atoms bonded to Z, the compound becomes a stronger acid. Hydrogen atoms and all oxygen atoms have +1 and -2 oxidation numbers respectively. Also number of P - OH bond increases the acidity of species decreases All Rights Reserved. here oxidation state is +3. In these cases, the oxidation state of phosphorus is less than +5. 3+P=6. Rules for assigning oxidation numbers. When it is bonded to Fluorine (F) it has an oxidation number of +1.Here it is bonded to P so the oxidation number on Oxygen is -2.
