For which of the following sets of acids does water act as a "leveling solvent," rendering them seem — Ionic Equilibrium Chemistry Question

💡 Solution & Explanation

A leveling solvent fully ionizes strong acids, bringing their effective acidic strength down to that of the solvent's conjugate acid (e.g., $H_3O^+$). Water completely ionizes mineral acids like $HCl$, $H_2SO_4$, and $HNO_3$, making them appear equally strong in aqueous solution. Differentiating solvents like glacial acetic acid must be used to distinguish their intrinsic strengths.
