What is the main difference between a concentrated acid and a strong acid?
Answer and explanation
Correct answer: Concentration relates to amount and strength relates to ionisation
Concentration describes how much acid is present per unit amount of solution, whereas strength describes the degree to which the acid ionises in water. A concentrated weak acid may contain much solute but ionise only partly; a dilute strong acid may ionise almost completely while containing little solute. Therefore, concentration and strength are different ideas, making option A correct.
