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

This exercise is based on the Br\u00f8nsted-Lowry theory of acids and bases, which defines acids as proton (H\u207a) donors and bases as proton acceptors. When an acid donates a proton, the remaining species is called its conjugate base. Conversely, when a base accepts a proton, the new species formed is its conjugate acid. A conjugate acid-base pair consists of two substances that differ only by the presence or absence of a single proton.<\/p>\n\n\n\n

Finding a Conjugate Base from an Acid:<\/strong>
To find the conjugate base of an acid, you must remove one proton (H\u207a) from the acid’s chemical formula. This involves two steps: first, removing a hydrogen atom (H), and second, decreasing the overall charge of the species by one.<\/p>\n\n\n\n

    \n
  • NH\u2084\u207a<\/strong>: Removing one H\u207a from the ammonium ion (NH\u2084\u207a) leaves ammonia (NH\u2083). The charge changes from +1 to 0.<\/li>\n\n\n\n
  • H\u2082O<\/strong>: Water can act as an acid. Removing one H\u207a from H\u2082O results in the hydroxide ion (OH\u207b). The charge changes from 0 to -1.<\/li>\n\n\n\n
  • HBr<\/strong>: Hydrobromic acid (HBr) donates a proton to become the bromide ion (Br\u207b). The charge changes from 0 to -1.<\/li>\n<\/ul>\n\n\n\n

    Finding a Conjugate Acid from a Base:<\/strong>
    To find the conjugate acid of a base, you add one proton (H\u207a) to the base’s chemical formula. This involves adding a hydrogen atom (H) and increasing the overall charge by one.<\/p>\n\n\n\n

      \n
    • OH\u207b<\/strong>: The hydroxide ion (OH\u207b) accepts a proton to form its conjugate acid, water (H\u2082O). The charge changes from -1 to 0.<\/li>\n\n\n\n
    • H\u2082PO\u2084\u207b<\/strong>: The dihydrogen phosphate ion (H\u2082PO\u2084\u207b) accepts a proton to become phosphoric acid (H\u2083PO\u2084). The charge changes from -1 to 0.<\/li>\n\n\n\n
    • ClO\u2083\u207b<\/strong>: The chlorate ion (ClO\u2083\u207b) accepts a proton, forming its conjugate acid, chloric acid (HClO\u2083). The charge changes from -1 to 0.<\/li>\n<\/ul>\n\n\n\n
