Aluminum and Bisulfite Ions

The video tutorial explains how to write the formula for aluminum bisulfite. It begins by identifying the element symbol for aluminum and the bisulfite ion, which is not found on the periodic table. The bisulfite ion, also known as the hydrogen sulfide ion, is HSO3- with a negative charge. The tutorial then discusses the ionic charge of aluminum, which is 3+, and explains how to balance these charges to form a neutral compound. By using three bisulfite ions, the charges are balanced, resulting in the formula Al(HSO3)3. The video concludes with a brief thank you from Dr. B.
