With major component (Benzohydrol) and minor component (caffeine), explain why an acid-base reaction would be good to seperate the two components. Explain procedures for acid-base reaction steps that will help you achieve acid-base seperation. Please explain why acid-base reaction would be the best option in lieu of recrystallization based on chemical principles.
