HPO4 does not exist. HPO42- would be the dibasic form of phosphoric acid and be the hydrogen phosphate ion. H3PO4 also exists and is phophoric acid. So if two moles of NaOH were reacted with phosphoric acid 2Na+ HPO42- would be formed disodium hydrogen phosphate.

You see it's called Hydrogen Phosphate because of the Hydrogen(H) and the Phosphate(PO4). I like chocolate.

What is the name of the hpo42- ion?
monohydrogen phosphate
What is the strongest acid A HNO3 B HF C H2S D CH3COOH E HPO42?
hpo42
Which of the following is the conjugate base of HPO42-?
PO43-
How do you write the equation for the acid hydrolysis of phosphoric acid?
There are three protolysis steps:H3PO4 ---> H+ + H2PO4-H2PO4- ---> H+ + HPO42-HPO42- ---> H+ + PO43-
What is the conjugated acid of HPO42?
PO43-
What is the name of the hpo42- ion?
monohydrogen phosphate
What is the strongest acid A HNO3 B HF C H2S D CH3COOH E HPO42?
hpo42
What is the formula for hydrogenphosphate?

What is the conjugate base of 4?
PO43- (phosphate) is the conjugate base of HPO42- (monohydrogen phosphate)
Sodium di hydrogen phosphate dissociation?
NaH2PO4(aq) + H2OàH3PO4(aq) + NaOH(aq) H3PO4(aq)ßàH+(aq) + H2PO4_(aq) H2PO4-(aq)ßàH+(aq) + HPO42-(aq) HPO42-(aq)ßàH+(aq) + PO43-(aq)
What is a poly protic acid?
A polyprotic acid can (in a multi-step reaction) donate more than one proton per molecule of acid.E.g. phosphoric acid can do 'the trick' three times:H3PO4 --> H+ + H2PO4-H2PO4- --> H+ + HPO42-HPO42- --> H+ + PO43-
At pH 7.5 which species predominate of H3PO4?
HPO42- is the most abundant phosphate present at pH=7.5, but H2PO42- is also there in (less) significant amounts. PO43- and H3PO4 are practically absent at pH 7.5.This is because it is between the valuespH=pKa,3= 12.4 (at which value there is 50% HPO42- and 50% PO43-) andpH=pKa,2= 7.2 (at which value there is 50% HPO42- + 50% H2PO42-)[Cf.

What is the oxidation number of p in the hpo42?
H= +1 P= +5 O= -2 Source: Mastering Chemistry
Is Hpo3 an acid or a base?
Yes, mono- and di-dissociation may occur, finally resulting (at high pH levels) in PO43- and 2H+.H2PO4- --> H+ + HPO42- eventually followed by the second step (at higher pH levels):HPO42- + OH- --> PO43- + H2OIt is ALSO a monoprotic base by accepting a proton:H2PO4- + H+ --> H3PO4
