1. When adding the sodium borohydride solution to the vanillin solution, why are you told to do so in a dropwise fashion?
-So you don't accidentally spill any sodium borohydride
-To prevent formation of unwanted vanillin byproducts
-to prevent formation of unwanted sodium borohydride byproducts
-Sodium borohydride is explosive
-Both A and D above are correct
(I'm leaning towards option C but I also thought it might be D)
