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

It seems like I can’t access the image directly. However, based on the provided data, I can help you rank the solutions in order of increasing pH.<\/p>\n\n\n\n

The pH of a solution depends on whether it’s acidic or basic, and the strength of the acid or base. Here\u2019s a breakdown of the data:<\/p>\n\n\n\n

Acids<\/strong>:<\/p>\n\n\n\n

    \n
  1. Nitrous acid (HNO2)<\/strong> has a Ka value of ( 4.5 \\times 10^{-4} ), which means it is a weak acid.<\/li>\n\n\n\n
  2. Acetic acid (CH3COOH)<\/strong> has a Ka value of ( 1.8 \\times 10^{-5} ), which is weaker than nitrous acid.<\/li>\n<\/ol>\n\n\n\n

    Bases<\/strong>:<\/p>\n\n\n\n

      \n
    1. Aniline (C6H5NH2)<\/strong> has a Kb value of ( 4.3 \\times 10^{-10} ), which is very weak.<\/li>\n\n\n\n
    2. Ethylamine (C2H5NH2)<\/strong> has a Kb value of ( 6.4 \\times 10^{-4} ), which is stronger than aniline.<\/li>\n<\/ol>\n\n\n\n

      Salt Solutions<\/strong>:<\/p>\n\n\n\n

        \n
      • NaNO2<\/strong> is the salt of a weak acid (HNO2) and a strong base (NaOH). It will hydrolyze to form a basic solution.<\/li>\n\n\n\n
      • C6H5NH3Cl<\/strong> is the salt of a weak base (aniline) and a strong acid (HCl). It will hydrolyze to form an acidic solution.<\/li>\n\n\n\n
      • CH3NH3Cl<\/strong> is the salt of a weak base (methylamine) and a strong acid (HCl). It will also form an acidic solution.<\/li>\n\n\n\n
      • KCH3CO2<\/strong> is the salt of a weak acid (acetic acid) and a strong base (KOH), so it will form a basic solution.<\/li>\n<\/ul>\n\n\n\n

        Ranking by pH:<\/h3>\n\n\n\n
          \n
        1. 0.1 M C6H5NH3Cl<\/strong> (acidic, due to hydrolysis of aniline salt) – pH will be the lowest.<\/li>\n\n\n\n
        2. 0.1 M CH3NH3Cl<\/strong> (similar reason as C6H5NH3Cl, weak base + strong acid) – next lowest pH.<\/li>\n\n\n\n
        3. 0.1 M NaNO2<\/strong> (basic solution, formed from the salt of a weak acid) – pH will be higher.<\/li>\n\n\n\n
        4. 0.1 M KCH3CO2<\/strong> (also a basic solution, formed from the salt of a weak acid and strong base) – highest pH.<\/li>\n<\/ol>\n\n\n\n

          Conclusion:<\/h3>\n\n\n\n
            \n
          • Rank: 1. 0.1 M C6H5NH3Cl<\/strong>, 2. 0.1 M CH3NH3Cl<\/strong>, 3. 0.1 M NaNO2<\/strong>, 4. 0.1 M KCH3CO2<\/strong>.<\/li>\n<\/ul>\n\n\n\n

            These rankings are based on the behavior of acids and bases in aqueous solutions and how they affect the pH through hydrolysis or dissociation.<\/p>\n\n\n\n
