The main difference between concentrated acid and dilute acid is related to what?
Answer and explanation
Correct answer: Amount of dissolved acid
Concentration refers to the amount of solute present in a given amount of solution. A concentrated acid solution contains a relatively large amount of dissolved acid, while a dilute solution contains a smaller amount because more solvent is present. This idea is different from acid strength, which depends on ionisation. Colour and name do not define concentration, and dilution does not turn an acid into a base. Therefore option A is correct.
