First, place your sep funnel in the iron ring, check that the stopcock is SHUT, then add the organic and aqueous solutions. Now, place the stopper on top.

first be deprotonated with the strong base sodium hydroxide in order for it to dissolve. Phenols (pKa = 10) are considerably more acidic than ordinary alcohols (pKa = 16-18) because the conjugate base (called a phenolate) is resonance stabilized. Since sodium hydroxide is the conjugate base of water (pK a = 15.7), the deprotonation of vanillin will
