Lead (IV) Sulfate Naming and Charges

The video tutorial explains how to name the compound PbSO4. It begins by identifying Pb as lead, a transition metal, and SO4 as the sulfate ion, a polyatomic ion. The tutorial then details how to determine the charge of lead, which is 4+, to balance the two sulfate ions, each with a 2- charge. The final name of the compound is Lead (IV) Sulfate, with the Roman numeral indicating the charge of the lead ion.
