Iron II Chloride vs. Iron III Chloride: What's the Difference?

Edited by Huma Saeed || By Sawaira Riaz || Published on January 10, 2024
Iron II chloride (FeCl2) is a ferrous compound with divalent iron, while Iron III chloride (FeCl3) is a ferric compound with trivalent iron.

Key Differences

Iron II chloride, also known as ferrous chloride, has the chemical formula FeCl2. It consists of iron in the +2 oxidation state. Iron III chloride, known as ferric chloride, is denoted by the formula FeCl3 and contains iron in the +3 oxidation state. These oxidation states affect their chemical reactivity and applications.
