What is the oxidation number of H3PO3?

In H3PO3, also known as phosphorous acid, the oxidation number of hydrogen is +1 and the oxidation number of phosphorous is +3. This is because hydrogen typically has an oxidation number of +1 in compounds, and the sum of oxidation numbers in a neutral compound must be zero.


What is the oxidation number of P in H3PO3?

'3' H3PO3 To calculate oxidation no. First sepatate out the ion. In this case PO3^(3-). Using oxygen as tha standard at '-2'. Then the oxygen moiety is '3 X -2 = -6' Creating a little sum P + -6 = -3 (The charge on the ion) . Add '6' t NB 'P' is in the same group as 'N' . Elements in this Group have variable oxid'n numbers. Hence P -6 + 6 = -3 +6 P = +3 The oxidation number of 'P'.


What is the oxidation number of phosphorus in H3PO3?

Oxidation number of P in H3PO3 is +3. To calculate the oxidation number H= 1 except when bonded to metal O is -2 except when bonded to F The sum of all of the oxidation number on a molecule /ion is equal to the charge so as H3PO3 is a neutral molecule:- 0 = OxP + 3OxH + 3OxO = Oxp + 3 + (-6) Oxp = +3 H3PO3 is phosphorus acid. However when you try to make it in aqueous solution, it "tautomerises" , turning into phosphonic acid, HPO(OH)2- same formula H3PO3, but its got a P-H bond and a P=O bond. The oxidation number of P is still 3
