# What is the structure of HPO4?

## What is the structure of HPO4?

Hydrogenphosphate is a phosphate ion that is the conjugate base of dihydrogenphosphate. It has a role as a Saccharomyces cerevisiae metabolite and a cofactor. It is a divalent inorganic anion and a phosphate ion. It is a conjugate base of a dihydrogenphosphate.

### How many resonance structures does hydrogen phosphate have?

We can reduce the number of charges by moving electrons to convert a P-O single bond to a P=O. double bond. There are four P-O bonds, so we can draw four structures: S, T, U, and V. These are all equivalent and are the major contributors to the resonance hybrid.

#### How many resonance structures does po43?

four stable resonance structures can be drawn for PO43- ion.

How many electrons does HPO4 2 have?

Since the addition of the H atom brings our needed electrons up to 42 and the number of electrons up to 40 (37 from the PO4 + 1 valence + 2 from the covalent bond attaching it) the HPO4 molecule only needs a 2- charge.

Is hpo42 an acid or base?

HPO4–2 can accept two protons further(and becomes phosphoric acid, H3PO4), so according to Bronstd-Lowry theory it is an base. And also it can donate the last proton it i having to become phosphate ion,PO4–3, so it is acid also.

## What is the conjugate acid for hpo42?

When we add a proton, we must conserve both mass and charge, we add H+ to HPO2−4 so the conjugate acid is simply H2PO−4 .

### How many resonance structures can one write for the phosphate ion PO4 3 in which the phosphorus atom has a formal charge of 0?

4 resonance structures
PO43- Step 8 Starting at the upper right corner and moving clockwise we can make 4 resonance structures that expand the P octet to 10. In all of these the P has a formal charge of 0 and one oxygen is also 0.

#### What is the conjugate acid of HPO4?

Why is HPO4 a weak base?

Salts containing the anion H2PO4‾ are weakly acidic. The tendency of this ion to dissociate is greater than its tendency to hydrolyse, that is, its Ka2, is larger than its Kb. Salts containing the anion HPO4‾ are weakly basic. The tendency of this ion to hydrolyse is greater than its tendency to dissociate.

### What is the number of valence electrons in ho4p2?

V is the number of valence electrons of HO 4 P -2. Therefore, P = 6n + 2 – V = 6 * 5 + 2 – 32 = 0 So, there is no multiple bond in the molecule.

#### What is the conjugate of [H2PO4]2- and [HPO4] 2-?

H2PO4- and [HPO4]2-. H 2P0 4 – is an acid and when it is in water it forms a hydronium ion and HPO 4 -, which is the conjugate base.
