Eugenol is the primary component in cloves (a spice). Eugenol gives ketchup its distinctive flavor, it is the odor of clove cigarettes, and both the taste and the odor are evident when cloves are steeped in hot water to make clove tea. Eugenol is a weak acid with pka = 10.2. The acid ionization reaction of eugenol is: HO. + H,0 + H30 eugenol The entropy change of this reaction is AS < 0. Let's say you boiled some water and made clove tea in a teapot with a lid. After steeping the cloves, you then removed the cloves and added just the right amount of sugar. And then you forgot about the tea while you were studying for your chemistry test. The tea cooled down. Which graph shows how the pH of the sweetened tea changed from the point after you mixed in the sugar to the hot tea it until now when it is colder? pH 7. OA time pH OB 7 time pH 7. time pH 7- OD time
