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

Classification of Acids and Bases<\/h3>\n\n\n\n

Strong Acids:<\/strong><\/h4>\n\n\n\n
    \n
  1. HBr<\/strong> (Hydrobromic acid)<\/li>\n\n\n\n
  2. H\u2082SO\u2084<\/strong> (Sulfuric acid)<\/li>\n\n\n\n
  3. HClO\u2084<\/strong> (Perchloric acid)<\/li>\n\n\n\n
  4. HI<\/strong> (Hydroiodic acid)<\/li>\n\n\n\n
  5. HCl<\/strong> (Hydrochloric acid)<\/li>\n\n\n\n
  6. HNO\u2083<\/strong> (Nitric acid)<\/li>\n<\/ol>\n\n\n\n

    Explanation:<\/strong>
    Strong acids fully ionize in aqueous solutions, meaning they completely dissociate into their ions. For example, HCl<\/strong> dissociates as:
    [
    HCl \\rightarrow H^+ + Cl^-
    ]
    This complete ionization makes them excellent proton donors in reactions.<\/p>\n\n\n\n

    \n\n\n\n

    Weak Acids:<\/strong><\/h4>\n\n\n\n
      \n
    1. CH\u2083COOH<\/strong> (Acetic acid)<\/li>\n\n\n\n
    2. HCOOH<\/strong> (Formic acid)<\/li>\n\n\n\n
    3. HClO<\/strong> (Hypochlorous acid)<\/li>\n\n\n\n
    4. HF<\/strong> (Hydrofluoric acid)<\/li>\n\n\n\n
    5. HCN<\/strong> (Hydrocyanic acid)<\/li>\n<\/ol>\n\n\n\n

      Explanation:<\/strong>
      Weak acids only partially ionize in aqueous solutions, meaning an equilibrium exists between the undissociated acid and its ions. For example, acetic acid dissociation:
      [
      CH_3COOH \\rightleftharpoons CH_3COO^- + H^+
      ]
      Since only some molecules dissociate, weak acids have a lower concentration of hydrogen ions in solution.<\/p>\n\n\n\n

      \n\n\n\n

      Strong Bases:<\/strong><\/h4>\n\n\n\n
        \n
      1. Ba(OH)\u2082<\/strong> (Barium hydroxide)<\/li>\n\n\n\n
      2. Ca(OH)\u2082<\/strong> (Calcium hydroxide)<\/li>\n\n\n\n
      3. KOH<\/strong> (Potassium hydroxide)<\/li>\n\n\n\n
      4. LiOH<\/strong> (Lithium hydroxide)<\/li>\n\n\n\n
      5. NaOH<\/strong> (Sodium hydroxide)<\/li>\n\n\n\n
      6. CsOH<\/strong> (Cesium hydroxide)<\/li>\n<\/ol>\n\n\n\n

        Explanation:<\/strong>
        Strong bases fully dissociate into hydroxide ions (OH\u207b) in aqueous solutions. For example, sodium hydroxide:
        [
        NaOH \\rightarrow Na^+ + OH^-
        ]
        Since strong bases completely ionize, they are efficient at neutralizing acids.<\/p>\n\n\n\n

        \n\n\n\n

        Weak Bases:<\/strong><\/h4>\n\n\n\n
          \n
        1. CH\u2083NH\u2082<\/strong> (Methylamine)<\/li>\n\n\n\n
        2. NH\u2083<\/strong> (Ammonia)<\/li>\n\n\n\n
        3. (CH\u2083)\u2082NH<\/strong> (Dimethylamine)<\/li>\n<\/ol>\n\n\n\n

          Explanation:<\/strong>
          Weak bases partially ionize in solution and establish an equilibrium between the base and its conjugate acid. For example, ammonia:
          [
          NH_3 + H_2O \\rightleftharpoons NH_4^+ + OH^-
          ]
          Since ionization is incomplete, weak bases have a lower concentration of hydroxide ions in solution.<\/p>\n\n\n\n

          This classification is based on ionization behavior, chemical properties, and experimental data.<\/p>\n\n\n\n

          Now, I’ll generate an image illustrating this classification.<\/p>\n\n\n\n
