What is the oxidation state of chlorine in ClO3?
Understand the Problem
The question is asking for the oxidation state of chlorine in the compound ClO₃ (chlorate). To determine this, we need to look at the oxidation states of the other elements in the compound. Oxygen typically has an oxidation state of -2. Since there are three oxygen atoms, we can calculate the overall contribution from oxygen and then solve for the oxidation state of chlorine.
Answer
+5
The oxidation state of chlorine in ClO3- is +5.
Answer for screen readers
The oxidation state of chlorine in ClO3- is +5.
More Information
The oxidation state of chlorine in the chlorate ion is +5 due to the combined effects of the oxidation states of the oxygen atoms and the overall charge of the ion.
Tips
A common mistake is to forget to account for the overall charge of the ion when setting up the sum equation for oxidation numbers.
