Sulfuric acid

Explanation:

Both sulfuric acid, and its conjugate base, HSO4 are strong acids in water for which the equilibrium lies strongly on the right:

H2SO4(aq)+2H2O(l)2H3O++SO24. Pure sulfuric acid is a water like solvent that undergoes the equilibium:

2H2SO4(l)H3SO+4+HSO4.

In this solvent regime (which would require specialized equipment and water free conditions to study), the acid is H3SO+4, and the base, bisulfate ion, HSO4.
