Determine the oxidation state of chlorine in ClO₃⁻.

Question

Quizplus · Accepted Answer

In this compound, the total charge of the anion is -1. Oxygen has an oxidation state of -2, sulfur has an oxidation state of +6, and the total oxidation state of the anion is -1. Therefore, the oxidation state of chlorine can be calculated as follows: Let x be the oxidation state of chlorine. (-1) = x + (-2) + 6 (-1) = x + 4 x = -5 Therefore, the oxidation state of chlorine in ClOS⁻ is -5, which is option E. However, since the question asks for the oxidation state of chlorine in ClOSB, we need to change the oxidation state of oxygen from -2 to -1 since it is bonded to a less electronegative sulfur atom. (-1) = x + (-1) + 6 (-1) = x + 5 x = +4 Thus the oxidation state of chlorine in ClO₃⁻ is +4, which is option B.
