Identification of an Unknown Organic Acid Essay

Identification of Unknown Organisms Benjamin Nibarger Professor Hoffman Monday 11:15 AM Group Members - Jamie Jerome, Natalie Perez, Ruth Pinzon September 27, 2014 Introduction The purpose of this study is to identify four unknown organisms. The unknown organisms have been assigned randomly to six-research groups by Professor Hoffman. Each research group was provided two eukaryotes and two prokaryotes. The unknown organisms will fall into the following classifications: bacteria, algae, fungi…

Lab Report 2: The Isolation and Identification of an Unknown Bacteria Abstract This laboratory experiment’s objective was to take a pure culture and isolate it from a mixed culture. The other part of the objective was to ascertain what species of bacteria that the pure culture was. The hypothesis made stated that so long as lab protocol was followed, the unidentified culture would be positively recognized/identified. An isolated pure colony of the unknown culture was obtained using the quadrant…

Determination of An Unknown Amino Acid From Titration Abstract Experiment 11 used a titration curve to determine the identity of an unknown amino acid. The initial pH of the solution was 1.96, and the pKa’s found experimentally were 2.0, 4.0, and 9.85. The accepted pKa values were found to be 2.10, 4.07, and 9.47. The molecular weight was calculated to be 176.3 while the accepted value was found to be 183.5. The identity of the unknown amino acid was established to be glutamic acid, hydrochloride…

Abstract This paper describes the methods used in the identification, investigation of properties, and synthesis of an unknown compound. The compound was identified as calcium nitrate by a variety of tests. When the compound was received, it was already known to be one of twelve possible ionic compounds. The flame test identified the presence of the calcium anion in the compound. The compound tested positive for the nitrate cation using the iron sulfate test. At this point it was hypothesized…

Recrystallization and Identification of Unknown Arsalan Kouser Chemistry 2270 Laboratory, Section 18 Instructor: Kyle Fulle October 8, 2014 Abstract In this laboratory project, Compound “E” was identified as N-Phenylsuccinimide. The % yield was 60.5 %. The melting point of both Compound “E” and N-Phenylsuccinimide was 153-154 ⁰C, as verified through experimentation; the official melting point range of N-Phenylsuccinimide is 153-157 ⁰C. The yield of dibromobenzene…

spectrometry. We will do this by making 2, 4 a DNPH derivative and checking the melting points. Theory: By Using specific methods of compounds detection, we can match an unknown compound with a known compound because similar compounds will display similar characteristics. In this experiment, identifications of the unknown ketone was accomplished using thin layer chromatography, melting point, and NMR spectrometry. Thin layer chromatography is very quick but sensitive way of determining the components…
