The video tutorial explains how to write the chemical formula for sulfuric acid (H2SO4) using a flow chart. It begins by identifying the number of elements and the absence of 'hydro' in the name, indicating a polyatomic ion. The tutorial then identifies the sulfate ion (SO4 2-) and its charge, and explains how to balance the charges by adding hydrogen ions to form H2SO4. The process is broken down into clear steps, ensuring a comprehensive understanding of the formula derivation.
