    Question

    Identify the strong acid from the list

    below:
    A Acetic acid Correct Answer Incorrect Answer
    B Hydrochloric acid Correct Answer Incorrect Answer
    C Citric acid Correct Answer Incorrect Answer
    D Carbonic acid Correct Answer Incorrect Answer

    Solution

    Hydrochloric acid (HCl) is recognized as a strong acid because it completely dissociates into hydrogen ions (H⁺) and chloride ions (Cl⁻) in water, which significantly contributes to its high acidity with a typical pH of about 1 in concentrated solutions. In contrast, acetic acid is only partially dissociative, exhibiting weaker acidic properties. Citric acid, common in citrus fruits, and carbonic acid, formed by CO₂ dissolution in water, are also weak acids, only partially releasing H⁺ ions in solutions.
