Ferrous Chloride Chemical Nomenclature

This video tutorial explains how to write the formula for ferrous chloride, also known as iron II chloride. It discusses the older naming system where 'ferrous' indicates a lower ionic charge, specifically Fe2+. The tutorial covers the ionic charges of iron, the use of the crisscross method to balance charges, and the resulting formula FeCl2. It also compares the older naming system with the modern one, where ferrous chloride is referred to as iron II chloride.
