The video tutorial explains how to write the formula for aluminum phosphate. It begins by identifying aluminum on the periodic table and recognizing phosphate as a polyatomic ion. The tutorial emphasizes the ionic nature of the compound and the need for charge balancing, with aluminum having a 3+ charge and phosphate a 3- charge. The charges balance to zero, resulting in the formula AlPO4. The video concludes with a summary of the process.
