Extra Important Information and Notes for Recrystallization Recrystallization Lecture Notes for Douglass Lecture 9-14-16 due to power outage is posted in Posting 05a and will only be online until 10/3/16 Completion of Recrystallization is posted in Posting 05b and will only be online until 10/3/16. Online Prelab Questions - Assignment 2 on OWLv2. Due date and time - one hour before the lab period begins on the day of recrystallization lab for your section. Sketches: Label the parts of the apparatus using parts of microscale kit from pg. 12 of your textbook when you draw out the sketches in your lab notebook. If the name on the figures themselves are different from the apparatus found on pg. 12, add them as an alternate name – many times these alternate names indicate the purpose of the parts of apparatus in that particular experiment. Read captions associated with the sketches you are drawing since some of the answers to questions you would need can be found there. MSDS links for Chemical Hazards: (Acetanilide) (Ethanol) Table of Reagents: The solid (Acetanilide) you are using (so melting point and solubility need to be listed) and the solvents (water and ethanol) you are using for recrystallization have to be in the table. The solvents need name, molecular weight, boiling point and densities in the table since they are liquids. For Acetanilide, list for solubility, the solubility of Acetanilide in water

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
