In aqueous solution, a substance that liberates positive hydrogen ions is classified as a(n) ___

Explanation:
Acids are substances that release hydrogen ions in water. In aqueous solution, free protons don’t exist alone; they attach to water to form hydronium ions (H3O+). So when a substance donates H+, it increases the hydronium concentration, lowering the pH of the solution. That proton-donating behavior defines an acid. Bases, in contrast, produce OH− or accept protons; salts and buffers have different roles and don’t simply donate H+ to the solution.
