Consider the reaction below. NH4+ + H2O mc013-1.jpg NH3 + H3O+ Which is an acid-conjugate base pair? NH4+ and NH3 NH4+ and H3O+ H2O and NH3 H2O and H3O+<\/p>\n\n\n\n

The Correct Answer and Explanation is :<\/strong><\/mark><\/p>\n\n\n\n

In the given reaction:<\/p>\n\n\n\n

[ \\text{NH}_4^+ + \\text{H}_2\\text{O} \\rightleftharpoons \\text{NH}_3 + \\text{H}_3\\text{O}^+ ]<\/p>\n\n\n\n

the correct acid-conjugate base pair is NH\u2084\u207a and NH\u2083<\/strong>.<\/p>\n\n\n\n

Explanation<\/h3>\n\n\n\n

Acid-Base Definitions<\/strong>: According to the Br\u00f8nsted-Lowry theory, an acid is a substance that donates a proton (H\u207a), while a base is a substance that accepts a proton. An acid-conjugate base pair consists of two species that differ by a single proton.<\/p>\n\n\n\n

In this reaction, NH\u2084\u207a (ammonium ion)<\/strong> acts as the acid because it donates a proton to H\u2082O (water)<\/strong>. When NH\u2084\u207a donates a proton, it transforms into NH\u2083 (ammonia)<\/strong>, which is its conjugate base. Therefore, NH\u2084\u207a and NH\u2083 are an acid-conjugate base pair.<\/p>\n\n\n\n

To clarify:<\/p>\n\n\n\n

    \n
  1. NH\u2084\u207a<\/strong> (acid) donates a proton:
    [
    \\text{NH}_4^+ \\rightarrow \\text{NH}_3 + \\text{H}^+
    ]<\/li>\n\n\n\n
  2. NH\u2083<\/strong> (conjugate base) is what remains after the donation of the proton.<\/li>\n<\/ol>\n\n\n\n

    Other Options<\/h3>\n\n\n\n
      \n
    • NH\u2084\u207a and H\u2083O\u207a<\/strong>: This pair does not fit the acid-conjugate base definition, as H\u2083O\u207a (hydronium ion) does not serve as the conjugate base of NH\u2084\u207a.<\/li>\n\n\n\n
    • H\u2082O and NH\u2083<\/strong>: Here, H\u2082O is a neutral molecule and NH\u2083 is a base. They are not an acid-conjugate base pair since they do not differ by a proton.<\/li>\n\n\n\n
    • H\u2082O and H\u2083O\u207a<\/strong>: This pair includes water and hydronium ion. Although water can act as a base, H\u2083O\u207a is not the conjugate base of H\u2082O but rather the product of its protonation.<\/li>\n<\/ul>\n\n\n\n

      Conclusion<\/h3>\n\n\n\n

      Thus, the correct acid-conjugate base pair from the reaction is NH\u2084\u207a and NH\u2083<\/strong>, as they illustrate the concept of acid-base pairs by differing by a single proton.<\/p>\n","protected":false},"excerpt":{"rendered":"
