WebJun 24, 2014 · 9. Hydrochloric acid is the stronger of the two. It has a p K X a around -6.3 while the p K X a of sulfuric acid is only around -3. Here are the chemical equations for the dissociations of the two acids. You can see that the second dissociation in the case of sulfuric acid is not very extensive and doesn't contribute much to the acidity of ... WebJun 17, 2024 · H X 2 S O X 4 is one of common strong acids, meaning that K X a ( 1) is large and that its dissociation even in moderately concentrated aqueous solutions is almost complete. Arrhenius dissociation: H X 2 S O X 4 ↽ − − ⇀ H X + + H S O X 4 X − K X a ( 1) = l a r g e Brønsted-Lowry Dissociation:
