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

      In acid-base chemistry, the concept of conjugate acids and bases<\/strong> comes from the Br\u00f8nsted-Lowry theory<\/strong>, which defines acids as proton (H\u207a) donors<\/strong> and bases as proton acceptors<\/strong>. When a base gains a proton, it becomes its conjugate acid<\/strong>. Conversely, when an acid loses a proton, it becomes its conjugate base<\/strong>.<\/p>\n\n\n\n

      1. Conjugate Acid of S\u00b2\u207b (Sulfide Ion)<\/strong>:<\/h4>\n\n\n\n

      The sulfide ion (S\u00b2\u207b) is a strong Br\u00f8nsted-Lowry base<\/strong> because it can accept protons (H\u207a). When it accepts one proton<\/strong>, it forms HS\u207b (hydrosulfide ion)<\/strong>. Therefore: S2\u2212+H+\u2192HS\u2212\\text{S}^{2-} + \\text{H}^+ \\rightarrow \\text{HS}^-<\/p>\n\n\n\n

      HS\u207b is the conjugate acid<\/strong> of S\u00b2\u207b. If HS\u207b gains another proton, it would become H\u2082S (hydrogen sulfide), a weak diprotic acid.<\/p>\n\n\n\n

      \n\n\n\n

      2. Conjugate Base of HPO\u2084\u00b2\u207b (Hydrogen Phosphate Ion)<\/strong>:<\/h4>\n\n\n\n

      HPO\u2084\u00b2\u207b is a weak acid that can donate a proton. When it loses one proton<\/strong>, it forms PO\u2084\u00b3\u207b (phosphate ion)<\/strong>. This is the conjugate base<\/strong> of HPO\u2084\u00b2\u207b. The reaction is: HPO42\u2212\u2192PO43\u2212+H+\\text{HPO}_4^{2-} \\rightarrow \\text{PO}_4^{3-} + \\text{H}^+<\/p>\n\n\n\n

      So, PO\u2084\u00b3\u207b is the species that remains after HPO\u2084\u00b2\u207b donates a hydrogen ion, making it the conjugate base.<\/p>\n\n\n\n

      \n\n\n\n

      Summary:<\/h3>\n\n\n\n
        \n
      • Conjugate acid of S\u00b2\u207b<\/strong> = HS\u207b<\/strong><\/li>\n\n\n\n
      • Conjugate base of HPO\u2084\u00b2\u207b<\/strong> = PO\u2084\u00b3\u207b<\/strong><\/li>\n<\/ul>\n\n\n\n

        These relationships are crucial for understanding chemical equilibria, buffer systems, and acid-base reactions in both inorganic and biological systems.<\/p>\n\n\n\n
