Which statement correctly explains the difference between a strong base and a concentrated base?
Answer and explanation
Correct answer: Strength is related to ionisation, while concentration is the amount per unit volume
Strength describes the extent to which a base ionises in water; a strong base, such as sodium hydroxide, ionises almost completely. Concentration describes how much dissolved base is present in a given volume of solution. Thus a strong base may be dilute, and a weak base may be concentrated. The two properties are independent, so option A is the accurate distinction.
