Verified step by step guidance
1
Understand the concept of acid dissociation: In aqueous solutions, acids dissociate into ions. A strong acid is one that completely dissociates into its ions.
Identify the characteristics of strong acids: Strong acids are known for their ability to fully dissociate, meaning they release all their hydrogen ions into the solution.
Evaluate the options given: Consider each statement and determine if it aligns with the definition of a strong acid. A strong acid does not partially dissociate, nor does it have a high pH value.
Recognize the role of conjugate bases: A strong acid forms a weak conjugate base because the acid has donated its proton completely, leaving behind a base that is less likely to accept a proton.
Conclude with the correct characteristic: The defining feature of a strong acid in aqueous solution is its complete dissociation into ions, which is the correct answer.
