H2PO4 Conjugate Base

By BYJU'S Exam Prep

Updated on: September 13th, 2023

The conjugate base is created when a base receives a proton, and conjugate acid is created when an acid loses a proton and leaves behind a product. Dihydrogen phosphate ion, also known as the given molecule H2PO4, has a molecular weight of 97 g. Two OH bonds can be seen in this ion or molecule. The majority of dihydrogen phosphate salts are non-toxic, colorless, and water-soluble.

Answer – H2PO4 conjugate base is HP(O^-2)4.

Let’s now examine the bronsted-lowry concept. The bronsted-lowry notion states that two acids’ propensities to give protons can be used to compare their respective strengths. Similar to this, the propensities of two bases to make protons are compared to determine their relative strengths. The conjugate base is the material that forms after an acid loses a proton (H+), and conjugate acid is the substance that forms after a base receives a proton (H+).

As a result, we learned that removing H+ from a molecule results in the formation of the conjugate base. To restore electrical neutrality after the removal of a proton, the remaining substance acquires a negative charge. HP(O^-2)4 is thus the conjugate base of H2PO4.


H2PO4 Conjugate Base

H2PO4 conjugate base is HP(O^-2)4. Both a conjugate base and a conjugate acid are created from an acid and a base, respectively.
