Surname2Organic Chemistry Lab ReportIntroductionOrganic chemistry is a field of science that deals with the study of compounds containingcarbon atoms. Mostly the most common compounds that are given a lot of consideration are hydrocarbons which are made only of hydrogen and carbon[ CITATION Jon12 \l 1033 ]. In the study of organic chemistry both the physical and chemical properties of these organic compounds are analyzed as well as understanding how these components are chemically constituted. PurposeThe purpose of this lab experiment is to equip the student with extraction process skills needed in separating an organic material from an aqueous solution and being able to determine the distribution coefficient.Materials and MethodsTest tubes125ml Erlenmeyer flask Separatory flaskBeakerExtraction of Water Soluble Dyes1 ml of ether, 1 ml of distilled water and 1 drop of 0.006 M solution of methylene blue were placed in a test tube and the shaken thoroughly for one minute to mix the contents. The
Surname3process was repeated by using 1 drop of 0.006 M solution of methylene red. The contents of the two test tubes were poured together and the resulting mixture shaken for one minute.Salting out Effect in Extractions5 ml of distilled water, 1 drop of 0.003 M aqueous crystal violet and 0.5 ml of 1-butanol were placed in two different test tubes and shaken until the color of the crystal violet had been evenly distributed in the two layers. Solid NaCl was added to one test tube up to saturation and both tubes shaken for one minute. Amount of crystal violet in the aqueous layers of the two samples was comparedDetermining the Distribution Coefficient35 ml of 1% aqueous adipic acid was added into a dry covered beaker and 10ml of the solution pipetted into a 125ml Erlenmeyer flask and the adipic acid titrated using 0.05 M NaOH in the presence of phenolphthalein indicator. A second 10ml adipic acid sample was titrated into a separatory funnel and 10ml of diethyl ether added before the separatory funnel was shaken once and then immediately vented. The separatory funnel was then shaken for two minutes with the aim of extracting the adipic acidinto the ether layer (Laboratory Manual). The aqueous layers was left to separate after which it was transferred to a clean 125ml Erlenmeyer flask. A drop of phenolphthalein indicator was added into the flask and the aqueous layer titrated using 0.05 M of NaOH.The separatory funnel was cleaned and 10ml of adipic acid pipetted into it. 10ml of ether was added and the separatory funnel shaken. The ether layer was given time to separate and then discarded. The remaining aqueous layer was again extracted using 10ml of ether after which it
