Why is nitric acid stronger than phosphoric acid ? :

Nitric acid: There are two synergistic effects at play here First the nitrogen in the center of nitrate (the deprotonated form) is far more nucleophilic than the phosphorus in the center of phosphoric acid This will pull some of the electron density off of the oxygen atoms and lower their energy As you mentioned nitrate also has 3 equally
