What is the oxidation number of Cl in ClO2-?
Understand the Problem
The question is asking for the oxidation number of chlorine (Cl) in the chlorite ion (ClO2-). To solve this, we can use the rules for determining oxidation numbers, where oxygen typically has an oxidation number of -2. Given that there are two oxygen atoms, we can set up an equation to find the oxidation number of chlorine.
Answer
+3
The oxidation number of Cl in ClO2- is +3.
Answer for screen readers
The oxidation number of Cl in ClO2- is +3.
More Information
Each oxygen atom has an oxidation state of -2, and the ion carries an overall charge of -1. To satisfy this, chlorine must have an oxidation state of +3 to balance the partial charges.
Tips
A common mistake is to not account for the total charge of the ion correctly when assigning oxidation states.
