Zinc and Sulfate Compounds

The video tutorial explains how to name the compound ZnSO4, known as zinc sulfate. It begins by identifying the sulfate ion (SO4) as a polyatomic ion and zinc as a transition metal. The tutorial outlines the process of naming ionic compounds by first naming the metal (zinc) and then the polyatomic ion (sulfate). It highlights zinc's unique property of consistently having a two-plus ionic charge, which balances with the two-minus charge of the sulfate ion, resulting in a neutral compound. The video concludes with a summary of the naming process and the importance of understanding ionic charges.
