What is the oxidation number of Cl in ClO-?
Understand the Problem
The question is asking for the oxidation number of chlorine in the hypochlorite ion (ClO-). To find this, we need to take into account the overall charge of the ion and the oxidation states of oxygen, which is usually -2.
Answer
+1
The oxidation number of Cl in ClO- is +1.
Answer for screen readers
The oxidation number of Cl in ClO- is +1.
More Information
The concept of oxidation numbers helps keep track of electron transfers in chemical reactions. The hypochlorite ion (ClO-) is commonly used as a bleaching agent and disinfectant.
Tips
A common mistake is to incorrectly assume the oxidation number of oxygen. Ensure it is consistent with standard conventions, generally -2 except in peroxides.
