Question

what is the oxidation state for cl in clo3? you do not need to include a positive sign for a positive oxidation number.

Explanation:

Step1: Set up the equation

Let the oxidation state of \(Cl\) be \(x\). In \(ClO_{3}^{-}\), oxygen has an oxidation state of \(- 2\). The sum of oxidation states in a polyatomic ion equals the charge of the ion. So, \(x+3\times(-2)=-1\).

Step2: Solve the equation
