The conjugate acid of NH3 is NH3+.<\/p>\n\n\n\n

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

The correct answer is: E) NH4\u207a<\/strong><\/p>\n\n\n\n

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

To understand conjugate acids and bases, we use the Br\u00f8nsted\u2013Lowry acid-base theory<\/strong>, which defines acids as proton (H\u207a) donors<\/strong> and bases as proton acceptors<\/strong>.<\/p>\n\n\n\n

Ammonia (NH\u2083)<\/strong> acts as a base<\/strong> because it has a lone pair of electrons on the nitrogen atom, which allows it to accept a proton (H\u207a)<\/strong>. When NH\u2083 accepts a proton, it becomes NH\u2084\u207a (ammonium ion)<\/strong>. This is the conjugate acid<\/strong> of ammonia.<\/p>\n\n\n\n

The reaction looks like this:NH3+H+\u2192NH4+\\text{NH}_3 + \\text{H}^+ \\rightarrow \\text{NH}_4^+NH3\u200b+H+\u2192NH4+\u200b<\/p>\n\n\n\n

    \n
  • In this reaction, NH\u2083 is the base<\/strong>, and after accepting H\u207a, it becomes NH\u2084\u207a, its conjugate acid<\/strong>.<\/li>\n<\/ul>\n\n\n\n

    Now, let\u2019s consider the answer choices:<\/p>\n\n\n\n

      \n
    • A) NH\u2082\u207b<\/strong>: This is the amide ion<\/strong>, a very strong base. It is not formed by NH\u2083 gaining a proton but by losing<\/strong> one (which makes it the conjugate base<\/strong> of NH\u2083, not its conjugate acid).<\/li>\n\n\n\n
    • B) NH\u2083\u207a<\/strong>: This is not a valid species<\/strong> in aqueous chemistry. It\u2019s not the correct conjugate acid.<\/li>\n\n\n\n
    • C) H\u207a<\/strong>: A proton itself, not a conjugate acid of NH\u2083.<\/li>\n\n\n\n
    • D) H\u2083O\u207a<\/strong>: This is the hydronium ion<\/strong>, formed when water gains a proton. It is unrelated to the conjugate acid of NH\u2083.<\/li>\n\n\n\n
    • E) NH\u2084\u207a<\/strong>: This is correct<\/strong>, as explained above.<\/li>\n<\/ul>\n\n\n\n

      So, the conjugate acid of NH\u2083 is NH\u2084\u207a<\/strong>, formed by the addition of a proton to the ammonia molecule.<\/p>\n\n\n\n
