CH 110K Lecture Notes - Lecture 1: Ethyl Acetate, Miscibility, Ionic Strength
Document Summary
Supplement b and a are on the end of the syllabus not in the book. Cheating talk: post lab can"t be copied from the book even if cited. Upside down and open the stopper thing. Repeat this process for 15 minutes: drain off (but not off off save it) the first batch of hcl and then add the next batch. The base will precipitate which we will filter out: do same with 30 ml of naoh but with hcl, don"t get confused!!!!! Clear: m1v1=m2v2, it"ll take 30 ml of the opposite to neutralize it. Measure ph every 5 ml: how do we get rid of the ethyl acetate, we have to dry it first. Add sodium sulfate and then filter: air dry in a beaker. Go over to the hood and blow air on it (air tube) High vapor pressure equilibrium (will take 15 minutes) Now we have crudes of the unknowns: we will recrystallize them next lab!
