What is the oxidation number of iron in FeCl3?

Understand the Problem

The question is asking for the oxidation number of iron in ferric chloride (FeCl3). To find this, we will determine the charge on iron based on the known oxidation states of chlorine and the overall neutrality of the compound.

More Information

The oxidation state of +3 for iron (Fe) in FeCl3 can be derived by considering the common oxidation state of chlorine (-1) and setting the overall balance to zero.

Tips

A common mistake is to forget that the sum of oxidation numbers in a neutral compound must be zero.
