Compounds do not have oxidation numbers; only single atoms and elements do.
However:
- hydrogen in compounds always has an ON of +1 (except in hydrides, where it is -1).
- oxygen always has an ON of -2 in compounds (except in peroxides and other certain compounds).
- phosphorous in this case has an ON of +5 (the total ON on oxygens is -8, but -3 is covered by the overall charge of the phosphate anion).

The valence of H3PO4 (phosphoric acid) is +5. This is derived by considering the oxidation states of each element in the molecule: hydrogen is +1, phosphorus is +5, and oxygen is -2.

∙ 6y agoH3PO4 doesn't have a valence, per se. If you refer to combining power or equivalence, then it would be considered to have a valence of 3, but this is not a common nomenclature.

What is the product of FeBr2 plus H3PO4?
FeBr2 + H3PO4 <--> Fe3(PO4)2 + HBr
What is the chemical compound for phosphoric acid?
The chemical compound for phosphoric acid is H3PO4.
What is the valence number for phosphorus?
Valence is the number of bonds to other atoms. It is not always numerically equal to the oxidation number.The valence of phosphorus in PCl3 is 3; of P in PCl5 is 5; of P in H3PO4 is 5 (one of the bonds to oxygen is P=O).
Formula for phosphoric acid?
The chemical formula for phosphoric acid is H3PO4.
What is the Valancy of phosphorus?
Valence is the number of bonds to other atoms. It is not always numerically equal to the oxidation number.The valence of phosphorus in PCl3 is 3; of P in PCl5 is 5; of P in H3PO4 is 5 (one of the bonds to oxygen is P=O).
What is the pH of H3PO4?
The pH of H3PO4 (phosphoric acid) depends on its concentration. For a 1M solution, the pH would be around 0.91. Since phosphoric acid is a weak acid that can donate three protons, its pH decreases with increasing concentration due to the dissociation of H+ ions.
What is the common name for H3PO4?
H3PO4 is phosphoric acid.
Is H3PO4 an acid?
H3PO4 is a triprotic weak acid.
Equation of H3PO4 plus NaOH?
H3PO4 + 3NaOH --------> Na3PO4 + 3H2O
What is the formula for the conjugate base of H3PO4?
The conjugate base of H3PO4 is H2PO4-. The formula for the conjugate base can be found by removing one proton (H+) from the acid molecule.
What is the name of compound formula H3PO4?
The compound H3PO4 is called phosphoric acid.
What is the molecular formulae of phosphorus?
The formula is H3PO4 O | HO-P-OH | OH O HO-P-OH H3PO4 OH
What is the product of FeBr2 plus H3PO4?
FeBr2 + H3PO4 <--> Fe3(PO4)2 + HBr
Why is H3PO4 not a buffer system?
H3PO4 is a weak acid, and a weak acid is not sufficient for a buffer.
