Quizplus · Accepted Answer

To determine the oxidation state of an element in a compound, we assume that each element has the oxidation state corresponding to its position in the periodic table. Oxygen has an oxidation state of -2, and the total charge of the compound is 0. We can set up the equation: (-1) + x + (-2) + (+1) + 3(-1) + (+3) + (-1) + (-2) + (+1) + 0 = 0 where x represents the oxidation state of Cl. Solving for x, we get: x = +5 Therefore, the oxidation state of Cl in ClO₃^- is +5.
