The oxidation state of Cr3+ is +3
Explanation:
- The oxidation state of any stable or free element is always equal to zero because it has no tendency to combine with any other element.
- But in the case of monoatomic elements e.g. elements containing only one atom, the oxidation state is equal to the number of charges mentioned above it.
- Such as Cr3+ has a charge of +3. So, its oxidation state is the same e.g. +3
