Which statement about a strong acid and a concentrated acid is correct?
Answer and explanation
Correct answer: Strength is related to ionisation and concentration is related to amount
Acid strength describes the degree to which acid molecules ionise in water; a strong acid ionises almost completely under suitable conditions. Concentration describes the amount of dissolved acid present in a given volume of solution. Therefore, a solution may be concentrated but contain a weak acid, or dilute but contain a strong acid. Option B is correct; the other statements incorrectly treat strength and concentration as identical or opposites.
