Ionic Charges and Naming of Iron Compounds

The video tutorial explains how to name the compound FeOH3. It begins by identifying the hydroxide ion and recognizing iron as a transition metal. The tutorial then details the process of naming the metal and the polyatomic ion, calculating the ionic charge, and finalizing the name as Iron III Hydroxide. The video concludes with a summary of the naming process.

What is the polyatomic ion present in FeOH3?

• Hydroxide

• Carbonate

• Nitrate
