Verified step by step guidance

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 does not partially dissociate; it completely dissociates, which is a key characteristic.
Consider the pH value: A strong acid will have a low pH value, typically less than 3, due to the high concentration of hydrogen ions.
Understand the conjugate base: A strong acid forms a weak conjugate base because the acid has donated its proton completely, leaving a base that is less likely to re-accept a proton.
