Verified step by step guidance

Understand the concept of acid dissociation: A strong acid is one that completely dissociates into its ions in an aqueous solution. This means that all the acid molecules break apart into hydrogen ions (H⁺) and their corresponding anions.

Recognize the relationship between strong acids and conjugate bases: When a strong acid dissociates completely, it forms a weak conjugate base. This is because the conjugate base has little tendency to accept protons and reform the acid.

Consider the pH value: Strong acids have low pH values, typically less than 3, because they increase the concentration of hydrogen ions in the solution.

Differentiate between complete and partial dissociation: Strong acids completely dissociate, whereas weak acids only partially dissociate, leaving some of the acid molecules intact in the solution.

Apply these concepts to the options given: Identify that the characteristic of a strong acid in aqueous solution is its ability to completely dissociate into ions, which is the correct answer.
