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

To determine whether a salt solution is acidic<\/strong>, basic<\/strong>, or neutral<\/strong>, we must analyze the acid-base nature of its constituent ions<\/strong>. Specifically, we consider whether each ion is the conjugate of a strong or weak acid\/base.<\/p>\n\n\n\n

a. NH\u2084OAc (Ammonium acetate)<\/strong><\/h4>\n\n\n\n
    \n
  • NH\u2084\u207a is the conjugate acid of weak base NH\u2083 \u2192 acidic<\/strong><\/li>\n\n\n\n
  • OAc\u207b (acetate) is the conjugate base of weak acid acetic acid \u2192 basic<\/strong><\/li>\n\n\n\n
  • Since both are weak, and their strengths roughly cancel, solution is neutral<\/strong>.<\/li>\n<\/ul>\n\n\n\n

    b. KNO\u2083 (Potassium nitrate)<\/strong><\/h4>\n\n\n\n
      \n
    • K\u207a and NO\u2083\u207b come from strong base (KOH) and strong acid (HNO\u2083) \u2192 neutral<\/strong><\/li>\n<\/ul>\n\n\n\n

      c. CsNO\u2083 (Cesium nitrate)<\/strong><\/h4>\n\n\n\n
        \n
      • Similar to b: Cs\u207a from strong base (CsOH), NO\u2083\u207b from strong acid \u2192 neutral<\/strong><\/li>\n<\/ul>\n\n\n\n

        d. CsHCO\u2083 (Cesium bicarbonate)<\/strong><\/h4>\n\n\n\n
          \n
        • HCO\u2083\u207b is the conjugate base of H\u2082CO\u2083 (a weak acid), so it can accept H\u207a \u2192 basic<\/strong><\/li>\n<\/ul>\n\n\n\n

          e. Cs\u2082CO\u2083 (Cesium carbonate)<\/strong><\/h4>\n\n\n\n
            \n
          • CO\u2083\u00b2\u207b is a stronger base (conjugate base of HCO\u2083\u207b) \u2192 basic<\/strong><\/li>\n<\/ul>\n\n\n\n

            f. Cs\u2082HPO\u2084 (Cesium hydrogen phosphate)<\/strong><\/h4>\n\n\n\n
              \n
            • HPO\u2084\u00b2\u207b is amphiprotic but leans basic in water \u2192 basic<\/strong><\/li>\n<\/ul>\n\n\n\n

              g. KH\u2082PO\u2084 (Potassium dihydrogen phosphate)<\/strong><\/h4>\n\n\n\n
                \n
              • H\u2082PO\u2084\u207b is the conjugate acid of a weak base (HPO\u2084\u00b2\u207b) \u2192 acidic<\/strong><\/li>\n<\/ul>\n\n\n\n

                h. Cs\u2083PO\u2084 (Cesium phosphate)<\/strong><\/h4>\n\n\n\n
                  \n
                • PO\u2084\u00b3\u207b is the conjugate base of a weak acid (HPO\u2084\u00b2\u207b) \u2192 basic<\/strong><\/li>\n<\/ul>\n\n\n\n
