PO43- (phosphate) is the conjugate base of HPO42- (monohydrogen phosphate)
The conjugate base for HSO4- is SO4^2-.
The conjugate base of H3BO3 is B(OH)4-.
The conjugate base of SO2-4 is HSO3-.
The conjugate base of NH4+ is NH3 (ammonia). A conjugate base is formed by the removal of a proton (H+) from the parent acid or cation.
The conjugate base of HPO2-4 is PO3-4. This is obtained by removing a proton (H+) from the acid (HPO2-4) to form its corresponding base (PO3-4).
The conjugate base of H2AsO4- is HAsO42-. It is formed by removing one proton (H+) from the acid H2AsO4-.
The conjugate base and conjugate acid for HS04 is: Conjugate acid is H2SO4 Conjugate base is SO42
The conjugate base of NH3 is NH2-, formed by removing a proton (H+) from NH3.
The conjugate base for CH3CH2COOH is CH3CH2COO-.
The conjugate base of HSO3- is SO32-.
The conjugate base of H2O is OH-. When H2O loses a proton, it forms the hydroxide ion OH-, which is the conjugate base of water.
The conjugate base of H3PO4 is H2PO4-. The formula for the conjugate base can be found by removing one proton (H+) from the acid molecule.
