Conjugate Acid Of Hpo4 2

Explanation: 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 .

Fundamentals According to the Bronsted-lowery theory, a conjugate acid is a species which is formed by reaction of proton with a base. a conjugate base is a species which is formed when acid loses a proton. The reaction representing the formation of conjugate acid and conjugate base is as follow:

Acid donates hydrogen ion and base is the acceptor of proton. The conjugate acid base pair differs by one proton. Conjugate acid is formed when a hydrogen ion is added to the base. Whereas, the conjugate base is formed when an acid donates its proton (hydrogen ion). Therefore, the base, hydrogen phosphate ion reacts with a proton to form a conjugate acid.


Which of the following is the conjugate acid of hpo4 − 2?

Hence, H2PO4− is the conjugate acid of HPO42−

What is the conjugate acid of H2PO4 -?

The conjugate acid of H2PO4− is H3PO4 which have one proton more than the base.

Is HPO42 and H2PO4 a conjugate acid base pair?

H2P04 is an acid and when it is in water it forms a hydronium ion and HPO4, which is the conjugate base.

Is hpo4 2 an acid or base?

It is a very weak acid. The pHa = 12.66; i.e. at this pH 50% is HPO4(-2) and 50% is PO4(-3). Hydrogen phosphate and dihydrogen phosphate ions are amphoteric.
