Understand the definition of a strong acid: A strong acid is one that completely dissociates into its ions in an aqueous solution.
Consider the dissociation process: In water, a strong acid will release all of its hydrogen ions (H⁺) into the solution, leaving no undissociated acid molecules.
Evaluate the options: A strong acid forming a weak conjugate base is consistent with the complete dissociation, as the remaining base is less likely to re-associate with H⁺ ions.
Analyze the pH value: A strong acid will have a low pH value, not a high one, due to the high concentration of H⁺ ions in the solution.
Compare complete vs. partial dissociation: A strong acid completely dissociates, whereas a weak acid only partially dissociates into ions.
