Question

Quizplus · Accepted Answer

In KClO3, the oxidation state of K is +1 (alkali metals have an oxidation state of +1 in ionic compounds). The oxidation state of Cl can be calculated by assuming the oxidation state of O to be -2. Thus, 3(-2) + x = 0, where x is the oxidation state of Cl. Solving for x gives a value of +5 for Cl. Therefore, the oxidation states of the atoms in KClO3 are K = +1, Cl = +5, and O = -2. Choice C is the only option that matches these values.
