Ionic Compounds and Polyatomic Ions

The video tutorial explains how to name the compound Na2SO3. It begins by identifying the components: sodium, a metal, and the polyatomic ion SO3, known as sulfite. The tutorial outlines the steps to name the compound, starting with the metal followed by the polyatomic ion, resulting in the name sodium sulfite. It also discusses the ionic charge of the sulfite ion and how to balance it with sodium ions to form the compound. The video concludes with a brief recap of the naming process.
