Document Summary
The purpose of this experiment is to separate, purify and identify two unknown compounds from a mixture consisting one neutral and one acid. These two unknown compounds are seperated from each other using liquid-liquid extraction, purified using recrystallization, and identified by considering their physical properties such as melting points that are given. (ii) experimental: Liquid-liquid extraction was done on the unknown mixture following the procedures provided in chemistry 235 lab manual 2015- 2016 pages 2-7 to 2: the only difference is that 10% naoh(aq) was used instead of 10% hcl(aq) and. The solvents used in this extraction were diethyl ether and 10% naoh(aq). They were chosen by performing a solubility test. After seperation, two compounds were purified through recrystallization with the procedure provided in chemistry 235 lab manual. Both compounds were recrystallized with a solvent pair with procedure from chemistry 235 lab manual 2015-2016 on page 6-3.
