conducted to determine the identity of an unknown aldehyde or ketone. The tests include a Tollens test‚ a Schiff test‚ an iodoform test‚ and a derivative melting point test. The data of the first three tests was inconclusive. The final derivative melting point test was utilized to successfully determine that the unknown was the ketone‚ Propiophenone. Introduction: Qualitative analysis is a method or series of methods used to determine the identity of an unknown compound (1). It is imperative that

Chemistry Lab Report Purpose The purpose of this lab is to determine the identity of an unknown liquid by measuring its density and its boiling point and try to match it with those solutions given in Table 2 of experiment 2. Procedure Part A In Part A‚ The main purpose was to find the determination of the density of the unknown (j41) and by doing that we had to determine volumes of the unknown liquid (j41) using three different volumetric devices which are graduated cylinder‚ pipette

Identification of a Conjugated Diene from Eucalyptus Oil Purpose: The purpose of this experiment was to prepare the Diels-Alder adduct of the unknown Conjugated diene in eucalyptus oil‚ to separate the adduct‚ and identify the unknown diene from the melting point of it¡¯s adduct. Introduction: This experiment was performed using techniques of heating under reflux‚ vacuum filtration‚ recrystallization‚ and melting point measurements. These techniques were used to separate the Diels-Alder

Identification of Victims Identifications of victims is an issue service providers and law enforcement struggle with daily. Trafficking is very much a hidden crime‚ meaning most individuals could not identify a trafficking victim‚ even if they lived in their own community. There is only very recently increased awareness of trafficking‚ its victims‚ how to identify them‚ and how to treat them. According to Heather Clawson and Nicole Dutch‚ trafficking victims are kept isolated with no freedom and

Aims The purpose of the two experiments was to determine the fundamental effects that temperature has on the growth and survival of bacteria. During the first experiment five different bacterial broth cultures of Escherichia coli‚ Pseudomonas fluorescens‚ Enterococcus faecalis‚ Bacillus subtilis and Bacillus stearothermophilus were individually incubated at temperatures of 5‚ 25‚ 37‚ 45 and 55°C for one week in an aim to distinguish the effect temperature has on growth and survival of the five different
