What is H3PO4 conjugate?

H2PO4− is conjugate base of H3PO4 .

What is Ka1 vs Ka2?

The Ka1 value on its own is large, and the Ka2 value is 10^-2 which by itself is also significant in the equilibrium. As such, unlike most other acids with multiple Hydrogens, sulfuric acid has a high Ka2 which makes it strong.

Is Ka1 or Ka2 bigger?

Therefore, Ka2 would be smaller than Ka1 in regards to their acidity. This concept is mainly seen in polyprotic acids and bases as they can give off more than one H+ (or accept, if base).

What is the conjugate base of H3PO3?

This indicates that the H2PO3- is a base. Its conjugate acid would be H3PO3. The conjugate acid is the acid formed when you add a proton (H+) to a base. The conjugate base of H2PO3- would be HPO3-2.

Is H3PO4 a conjugate acid or base?

In the case of H3PO4, it forms H2PO4- (dihydrogen phosphate anion) as its conjugate base after removing an acidic proton. What is this? Moreover, H3PO4 is a weak acid so according to the conjugate acid-base pair, its corresponding pair, H2PO4− is a strong conjugate base.

What is the Ka2?

Ka2 represents the dissociation of the 2nd H+.

What is the Ka1 of H3PO4?

Ka1,Ka2 and Ka3 values for H3PO4 are 10^-3, 10^-8 and 10^-12 respectively.

How are Ka1 and Ka2 related?

acid dissociation constants refer to the equilibrium constant for loss of the first, second, third, and so on proton. For example, H2SO4 can lose one proton to make HSO4–, which can then lose another proton to generate SO42–. Ka1 and Ka2 would be the equilibrium constants for these reactions.

Why is Ka2 lower than Ka1?

This is because the negatively charged HSO4- ion has much less tendency to donate a proton to H2O as compared to neutral H2SO4.

What is the Ka2 of H2CO3?

Carbonic acid (H2CO3), a diprotic acid has Ka1=4.0×10^−7 and Ka2=5.0×10^−11.

What is the conjugate base of hpo4 2 −?

The conjugate base of dihydrogen phosphate is HPO2−4 (so you know the conjugate acid, why?).

Why is Ka2 Ka1 for H2SO4?

Is H3PO4 a monoprotic acid?

Triprotic acids, such as phosphoric acid (H3PO4) and citric acid (C6H8O7), have three. There is usually a large difference in the ease with which these acids lose the first and second (or second and third) protons.

How do you get the Ka from pKa?

To create a more manageable number, chemists define the pKa value as the negative logarithm of the Ka value: pKa = -log Ka. If you already know the pKa value for an acid and you need the Ka value, you find it by taking the antilog.

Why is Ka1 >>> Ka2 in Sulphuric acid?

What is pKa1 and pKa2?

pKa1 is the α-carboxyl group, pKa2 is the α-ammonium ion, pKa3 is the side chain group if applicable and pI is the isoelectric point at which the amino acid has no net charge. At a pH lower than pI the amino acid is positively charged, at higher pH than pI the amino acid is negatively charged.
