hydrochloric acid is HCl, having 1 hydroge atom and phosphoric acid is H3PO4 having 3 hydrogen atom. so if we add same masses of these acids in same amounts of water, then phosphoric acid should yield more hydrogen ions and would be more acidic than HCl, but it is not so. Why?

The strength of an acid also depends on its ability to dissosciate into hydrogen ions so though phosphoric acid is stronger than acetic acid it is not stronger than HCl
