Which statement about dilute acid and concentrated acid is correct?
Answer and explanation
Correct answer: Dilute acid has less acid per amount of solution
The governing idea is concentration, which compares the amount of solute with a given amount of solution. A dilute acid contains a smaller proportion of acid and a larger proportion of solvent, so option A is correct. “Dilute” does not mean basic, and a concentrated acid can still contain some water. Concentration is also different from strength: a concentrated acid may be strong or weak depending on its ionisation in water.
