In this reaction, NH4+ + H2O -> H3O+ + NH3 the conjugate base of H3O+ ion is:
Correct answer: B. H2O
- A. NH4+
- B. H2O
- C. H+
- D. NH3
Explanation
A conjugate acid, within the Brønsted-Lowry acid-base theory, is a chemical compound formed when an acid donates a proton to a base-in other words, it is a base with a hydrogen ion added to it, as in the reverse reaction it loses a hydrogen ion. Hence, Option B (H2O) is correct while other options are rendered as incorrect.
