asked Apr 4, 2019 in Redox reactions and electrochemistry by Simrank ( 72.0k points) Many acids are derived from phosphate rocks by a wet process based on the reaction between phosphate rocks and acid solutions.1 This acid (H3PO4) is a medium-strong acid, but is also highly corrosive to ferrous or ferrous alloys. The orthophosphoric anhydrous acid is a white, crystalline solid which melts at 42.35°C. Click hereðto get an answer to your question ï¸ The oxidation state of P in H3PO4 is : H3PO4 contains the H+ ion with a charge of +1 and the PO4-3 polyatomic ion. Answer Save. Phosphorus also shows +1 and + 4 oxidation states in some oxo acids. I have also found evidence that it may be -3, +3. Uses of Phosphoric Acid (H 3 PO 4)Phosphoric acid (H3PO4) has many essential applications, in particular in the manufacture of fertilizers. Anonymous. The stability of + 5 oxidation state decreases down the group. O = -2. Favorite Answer. Explanation: The given compound is phosphoric acid, in which hydrogen is bonded with non-metal. Relevance. As a result, the most common oxidation states it can have are +3 (s2p0) or +5 (s0p0). Assigning oxidation numbers to organic compounds.

Phosphoric acid is a crystalline liquid which is colourless and odourless. Oxidation number of P in is +5. what are the oxidation states for each atom in H3PO4. The algebraic sum of the oxidation states in an ion is equal to the charge on the ion. 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. The stability of + 5 oxidation state decreases and that of + 3 state increases (due to invert pair effect) down the group. To calculate the oxidation number of P, an equation must be written which is as follows: On this account the name of para phosphoric has been given to it; while the term phosphoric is applied to designate the acid in the state first described. CHEERS!! ; As the given compound is neutral, its total charge is equal to 0. Since phosphorus is a member of group 5A, it has 5 electrons in its valence shell. 1 decade ago. 3 Answers. H = +1. H3PO4 H3PO2 H5P3O10 H4P2O7 H3PO4 H3PO2 H5P3O10 H4P2O7 FREE Expert Solution Show answer The oxidation numbers of the elements in H3PO4 are: H +1 P +5 O -2 The compound's systematic name is phosphoric(V) acid, to reflect the oxidation number of the phosphorus. The oxidation number for phosphorus in H3PO4 is +3. P = +5. Problem: Some of the known Phosphorous oxoacids are the following, list the oxidation state for phosphorous. 0 0. caroline m. Lv 6. What is the oxidation no. of phosphorus in H3PO3 , H3PO4 , H3PO2 or phosphorus, acid, Phosphoric acid, phosphinic acid respectively ? The sum of the oxidation numbers in a monatomic ion is equal to the overall charge of that ion. Oxidation-Reduction Reactions - ppt download Redox Review worksheet Some of the known Phosphorous oxoacids are the following, list the oxidation state for phosphorous., H3PO4, H3PO2, H5P3O10, H4P2O7 1 decade ago.
