Organic Lab 1: Fractional Distillation Discussion: With the purpose of the experiment being to identify the 30 mL of unknown liquid‚ the theoretical basis of simple and fractional distillation must be deconstructed and applied to the data obtained describing the liquid in question. Simple distillation is a separation technique which can be used to separate and purify distillates from a liquid mixture which ideally contains one volatile and one non-volatile compound. If such ideal conditions are

Diffusion and Osmosis Through Dialysis tubing We did this experiment to test the diffusion of different substances through dialysis tubing. We used what we knew about diffusion to make predictions on what we thought the mass of the dialysis tubing to be after submerging them for 30 mins and we knew that diffuse occurs from highest concentration to lowest concentration. Since the dialysis tubings are filled with different substances than what they are being put into then they should all gain

Title: Homeostasis Date: 19th January 2010 Aim: To observe‚ draw and label the parts of a nephron. Apparatus: Slide of the transverse section of a kidney Pencil Paper Microscope Method: The slide of the transverse section of a kidney was mounted on the microscope and observed under high power. Drawings of the parts of the nephron were made. Calculations of Magnification: Loop of Henle One Ocular Division = 0.22 µm Size of Specimen = 2 ocular divisions Conversion of Ocular

Enzymes Introduction This study allows the investigation of enzymatic reactions behavior. An enzyme is a protein catalyst reaction by lowering the activation energy required for that reaction. The enzyme is unaltered at the completion of the reaction. In this stimulation the amount of product produced during the course of an enzymatic product produced during the course of an enzymatic reaction will be measured. Hypothesis 1: What is the estimate optimal of ph? Hypothesis 2: What is the estimate optimal of temperature

causing the body to not have enough acids in the urine. These factors are all very different‚ but are interconnected because an imbalance in any of these factors can lead to imbalances in other areas as well (Wise‚ 2010). The importance of this lab is to analyze factors that may affect urine concentration‚ pH‚ and rate of production (flow rate) though multiple scenarios over a period of 60 minutes. My hypothesis for the urine analysis experiment is that the urine volumes will increase because

Lab 1 Diffusion‚ Osmosis‚ and Water Potential of Glucose Problem: What effects will glucose have on diffusion‚ osmosis‚ and water potential? Background: All living things have certain requirements they must satisfy in order to remain alive. These include exchanging gases (usually CO2 and O2)‚ taking in water‚ minerals‚ and food‚ and eliminating wastes. These tasks ultimately occur at the cellular level‚ and require that molecules move through the membrane that surrounds the cell. There

Purpose: To use indicators to test for the presence of organic compounds in certain substances. Hypothesis: Honey will contain sugars‚ egg white contains proteins‚ corn oil contains lipids‚ oats contains starches and proteins‚ gelatin contains sugars and proteins‚ potatoes contain starch‚ and apple juice contains lipids and sugars. Materials: 9 test tubes Test tube rack Test tube holder Grease pencil Hot plate 20 ml honey solution 20 ml egg white and water mixture 20

nCH3 The first step in the lab is the preparation of the solvent used in the developing chamber for thin layer chromatography. The solvent used is a 3:1 mixture of toluene and petroleum. After the developing chamber is prepared‚ it is essential to begin preparation of the unknown DNPH derivative[6]. The preparation of the 1‚2 DNPH derivative of a ketone is in fact a small organic synthesis which produces a fraction of a gram of product. The second part of the lab makes use of NMR Spectrometry
