Respuesta :
For the given chemical reaction, NH₄ - NH₃ and H₂O - H₃O is the acid - conjugate base pair.
What is acid - conjugate base pair?
An acid - conjugate base pair are those pairs which are differ by the only one proton or H⁺ ion.
Given chemical reaction is:
NH₄ + H₂O → NH₃ + H₃O
According to the Bronsted-Lowry theory, acids are those which gives H⁺ ion and bases are those which accept H⁺ ion in the aqueous solution. In the above reaction NH₄ is an acid as it losses H⁺ ion and NH₃ is the conjugate base of NH₄. Similarly, H₂O is a base as it accepts H⁺ ion and H₃O is the conjugate acid of H₂O.
Hence, NH₄ - NH₃ and H₂O - H₃O is the acid - conjugate base pair.
