Dihydrogen Phosphate Ion Concepts

The video tutorial explains how to write the formula for the dihydrogen phosphate ion. It begins by identifying the components of the ion, including the two hydrogen atoms and the phosphate ion (PO4 3-). The tutorial then calculates the overall ionic charge, resulting in a negative one charge for the dihydrogen phosphate ion (H2PO4-). The video concludes with a mention of additional resources for drawing the Lewis structure.
