What is the main basis of difference between a concentrated acid and a dilute acid?
Answer and explanation
Correct answer: Amount of acid in a given amount of solution
The governing concept is concentration: it describes the amount of solute present in a given amount of solution. A concentrated acid solution contains a relatively larger amount of acid, whereas a dilute solution contains a smaller amount, so option A is correct. Concentration must not be confused with strength. Strength concerns the extent to which an acid ionises in water; a weak acid may be concentrated, and a strong acid may be dilute.
