Question

Lower is the critical micelle concentration of surfactant, ..... is the detergency.
1. lower
2. higher
3. indeterminate
4. none of the above

Fill in the blank with the correct answer number.

Answer 1

A surfactant with a low critical micelle concentration gives rise to a washing solution of effective cleaning power, even at low concentrations of the detergent. Hence, the detergency is increased.
