What is the oxidation state of Cl in each ion? a. ClO- b. ClO2- c. ClO3- d. ClO4-<\/p>\n\n\n\n

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

Let’s go through the oxidation states of chlorine in each ion one by one:<\/p>\n\n\n\n

a. ClO\u207b (Hypochlorite ion)<\/strong><\/h3>\n\n\n\n

In the hypochlorite ion (ClO\u207b), oxygen has an oxidation state of -2. Since the ion has an overall charge of -1, the sum of the oxidation states of chlorine and oxygen must equal -1.<\/p>\n\n\n\n

    \n
  • Let the oxidation state of chlorine be x.<\/li>\n\n\n\n
  • The total charge equation will be:
    x + (-2) = -1
    x – 2 = -1
    x = +1<\/li>\n<\/ul>\n\n\n\n

    So, the oxidation state of chlorine in ClO\u207b is +1<\/strong>.<\/p>\n\n\n\n

    b. ClO\u2082\u207b (Chlorite ion)<\/strong><\/h3>\n\n\n\n

    In the chlorite ion (ClO\u2082\u207b), oxygen has an oxidation state of -2. With a charge of -1, the sum of the oxidation states of chlorine and the two oxygens must equal -1.<\/p>\n\n\n\n

      \n
    • Let the oxidation state of chlorine be x.<\/li>\n\n\n\n
    • The total charge equation will be:
      x + 2(-2) = -1
      x – 4 = -1
      x = +3<\/li>\n<\/ul>\n\n\n\n

      So, the oxidation state of chlorine in ClO\u2082\u207b is +3<\/strong>.<\/p>\n\n\n\n

      c. ClO\u2083\u207b (Chlorate ion)<\/strong><\/h3>\n\n\n\n

      In the chlorate ion (ClO\u2083\u207b), oxygen has an oxidation state of -2. With a charge of -1, the sum of the oxidation states of chlorine and the three oxygens must equal -1.<\/p>\n\n\n\n

        \n
      • Let the oxidation state of chlorine be x.<\/li>\n\n\n\n
      • The total charge equation will be:
        x + 3(-2) = -1
        x – 6 = -1
        x = +5<\/li>\n<\/ul>\n\n\n\n

        So, the oxidation state of chlorine in ClO\u2083\u207b is +5<\/strong>.<\/p>\n\n\n\n

        d. ClO\u2084\u207b (Perchlorate ion)<\/strong><\/h3>\n\n\n\n

        In the perchlorate ion (ClO\u2084\u207b), oxygen again has an oxidation state of -2. With a charge of -1, the sum of the oxidation states of chlorine and the four oxygens must equal -1.<\/p>\n\n\n\n

          \n
        • Let the oxidation state of chlorine be x.<\/li>\n\n\n\n
        • The total charge equation will be:
          x + 4(-2) = -1
          x – 8 = -1
          x = +7<\/li>\n<\/ul>\n\n\n\n

          So, the oxidation state of chlorine in ClO\u2084\u207b is +7<\/strong>.<\/p>\n\n\n\n

          Summary:<\/h3>\n\n\n\n
            \n
          • a. ClO\u207b<\/strong>: Oxidation state of Cl is +1<\/strong>.<\/li>\n\n\n\n
          • b. ClO\u2082\u207b<\/strong>: Oxidation state of Cl is +3<\/strong>.<\/li>\n\n\n\n
          • c. ClO\u2083\u207b<\/strong>: Oxidation state of Cl is +5<\/strong>.<\/li>\n\n\n\n
          • d. ClO\u2084\u207b<\/strong>: Oxidation state of Cl is +7<\/strong>.<\/li>\n<\/ul>\n\n\n\n

            Each of these species has chlorine in different oxidation states based on the number of oxygen atoms it is bonded to, which influences the overall charge distribution.<\/p>\n\n\n\n
