Understand the concept of acid and base dissociation: In aqueous solutions, acids and bases can dissociate into ions. The extent of this dissociation determines their strength.
Define strong acids and bases: Strong acids and bases dissociate completely in water, meaning they release all their ions into the solution.
Define weak acids and bases: Weak acids and bases only partially dissociate in water, meaning only a fraction of their molecules release ions.
Evaluate the given statements: Analyze each statement based on the definitions of strong and weak acids and bases.
Identify the correct statement: Based on the definitions, the statement 'A strong acid completely dissociates in water' is correct, as it aligns with the characteristic behavior of strong acids.
