Introduction:
The Family Smoking Prevention and Tobacco Control Act of 2009 allows the US FDA to regulate tobacco products, including the banning of characterizing flavors, such as fruit and candy, cigarettes. The availability of mint flavored snus may facilitate the use of the product if consumers find it more palatable with respect to taste, odor, pleasantness, and intensity.
Methods:
This study assessed product evaluation (PES), odor identification, odor intensity, and odor hedonics among 151 smokers enrolled in a clinical trial of snus substitution for cigarettes.
Results:
Far more participants selected Winterchill (N = 110) than Robust (N = 41), regardless of their menthol cigarette smoking status. Nicotine dependence was higher among those who selected Winterchill (4 vs 3 on Fagerstrom scale, p = 0.017). Those who found Winterchill to be more satisfying, less aversive, and having a more intense, more pleasant odor than Robust were substantially more likely to select Winterchill for their one week trial.
Conclusions:
Findings indicate that subjective effect measures such as the PES and DEQ are capable of differentiating products in terms of flavor preference, and that smokers express a strong preference for mint flavored snus.

Titration Calculations: Strong Acid - Strong Base
A titration is carried out for 25.00 mL of 0.100 M HCl (strong acid) with 0.100 M of a strong base NaOH. The pH at different volumes of added base solution can be calculated as follows:
(a) Titrant volume = 0 mL. The solution pH is due to the acid ionization of HCl. Because this is a strong acid, the ionization is complete and the hydronium ion molarity is 0.100 M. The pH of the solution is then:

Titration Calculations: Weak Acid - Strong Base
For the titration of 25.00 mL of 0.100 M CH3CO2H with 0.100 M NaOH, the reaction can be represented as:
Titration of a Weak Base with a Strong Acid
Using the ICE table and substituting the Kb value, we calculate the initial pH of 50 mL of 0.1 M ammonia to be 11.11. Addition of 25 mL of 0.1 M hydrochloric acid to this solution of ammonia results in a buffer with an equal concentration of ammonia and ammonium ions. The pH of this buffer can be calculated by substituting these...
