Chemistry 2003 JAMB Past Questions - Question 4: Tho filter in a cigarette reduces the nicotine content by

Correct Answer

B

Explanation

The filter in a cigarette primarily reduces the nicotine content through adsorption. Adsorption is a process in which molecules or particles adhere to the surface of a solid or liquid material. In the context of cigarette filters, certain materials, such as activated charcoal, are often used to adsorb some of the nicotine and other harmful chemicals present in the smoke.

While some nicotine may be reduced through this process, it's important to note that cigarette filters do not eliminate all of the harmful substances in cigarette smoke, and they do not make smoking safe. The health risks associated with smoking are still significant, even with the use of filters. Additionally, filters may alter the smoking experience and potentially lead to compensatory behaviors, where smokers inhale more deeply or smoke more to maintain their desired level of nicotine intake.
