Sorted by: 11. 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:
