The video tutorial explains how to write the chemical formula for silver sulfate. It begins by identifying silver and sulfate, noting that sulfate is a polyatomic ion with a 2- charge. The tutorial discusses the formation of ionic compounds and the importance of balancing charges. Silver, typically with a 1+ charge, combines with sulfate to form a neutral compound. The formula is balanced by using two silver ions for each sulfate ion, resulting in the formula Ag2SO4.
