Decoding FeCl3: The Not-So-Shocking Name Revealed
This article aims to provide a comprehensive explanation of the compound FeCl3, focusing primarily on its nomenclature and properties. Our core objective is to clearly answer the question: "What is the name of the compound FeCl3?". We will achieve this by systematically breaking down the chemical formula, exploring its naming conventions, and briefly discussing its key characteristics.
Understanding the Chemical Formula: FeCl3
The formula FeCl3 represents a chemical compound comprised of two elements: iron (Fe) and chlorine (Cl). The subscript '3' indicates the number of chlorine atoms bonded to each iron atom within the compound's structure. To accurately name this compound, understanding the role of each element is vital.
Iron (Fe) and its Oxidation States
Iron, a transition metal, exhibits multiple oxidation states. This means it can form ions with different positive charges. Common oxidation states of iron include +2 (ferrous) and +3 (ferric). Determining the oxidation state of iron in FeCl3 is crucial for its proper naming.
Chlorine (Cl) and its Role
Chlorine, a halogen, typically exists as a negative ion (anion) with a -1 charge when forming ionic compounds.
Determining the Name: Applying Chemical Nomenclature
The naming of FeCl3 depends on the oxidation state of iron. Because chlorine has a -1 charge and there are three chlorine atoms, the total negative charge is -3. Therefore, to maintain electrical neutrality, the iron atom must have a +3 charge.
The IUPAC Name: Iron(III) Chloride
According to the International Union of Pure and Applied Chemistry (IUPAC) nomenclature rules, when a metal exhibits multiple oxidation states, its oxidation state is indicated in parentheses using Roman numerals immediately after the metal's name.
Therefore, the most accurate and preferred name for FeCl3 is Iron(III) Chloride. This name clearly communicates that the iron atom is in its +3 oxidation state.
Alternative Naming (Less Common): Ferric Chloride
An older, less preferred naming convention uses suffixes to indicate the oxidation state. The suffix "-ous" is used for the lower oxidation state, and "-ic" is used for the higher oxidation state.
Since iron(III) is the higher oxidation state for iron, FeCl3 can also be referred to as Ferric Chloride. However, Iron(III) Chloride is considered more precise and unambiguous, and thus is favored. This method, however, can lead to confusion, especially with metals that exhibit multiple oxidation states.
Key Properties and Uses of Iron(III) Chloride
While the primary focus is nomenclature, it's helpful to understand a few of the compound's properties and applications.
-
Appearance: Anhydrous Iron(III) Chloride is a solid, with a color that can range from brown to black. It is also highly deliquescent, meaning it readily absorbs moisture from the air.
-

FeCl3 FAQs: Unmasking the Mystery
Here are some frequently asked questions to help you better understand FeCl3, also known as Ferric Chloride.
What exactly is FeCl3?
FeCl3 stands for Iron(III) Chloride. It's a chemical compound composed of iron and chlorine. It is a commonly used compound in various industrial applications.
What is the name of the compound FeCl3, and why is it sometimes called something else?
The official IUPAC name of FeCl3 is Iron(III) Chloride, also known as Ferric Chloride. It is called 'Ferric' because iron exists in two common oxidation states (+2 and +3), and 'ferric' refers to the +3 state. You might see it shortened to Ferric Chloride as well.
What are some common uses of FeCl3?
FeCl3 is used in wastewater treatment to help remove impurities and pollutants. It is also useful in etching circuit boards and even in some medical applications to stop bleeding.
Is FeCl3 dangerous to handle?
FeCl3 can be corrosive and irritating to the skin, eyes, and respiratory system. Appropriate safety precautions, like wearing gloves and eye protection, should always be taken when handling it. Always consult the SDS for detailed safety information.
