    Both the graph and the table represent the same thing‚ the temperature of the solution during fractional distillation. At the start of the fractional distillation‚ before we started the fire‚ it was 25° celcius. At the end of the fractional distillation‚ when all of the liquid was gone‚ it was 99.3 degrees. This set of data is not the first time we did the fractional distillation‚ it’s actually probably the 3rd or 4th. The first time we didn’t actually record the temperature‚ we just looked for the

    MAKING PROCESS AND DISTILLING PROCESS Vodka is defined in the United States Standards of Identity as “neutral spirits so distilled‚ or so treated after distillation with charcoal or other materials‚ as to be without distinctive character‚ aroma‚ taste‚ or color.” As Vodka is a neutral spirit‚ it means that it can be obtained by the distillation of any product with fermentable carbohydrates on it‚ like grains (rye‚ corn or wheat) or products like potatoes‚ beets or sugar beets; even grapes. Nowadays

    Distillation Alcoholic distillation is basically the process of separation the more volatile component‚ alcohol‚ from the less volatile component‚ water‚ from a water/alcohol solution‚ by heating the solution and condensing and collecting the alcohol rich vapours released‚ as a high alcohol strength liquid (spirit). The starting material for most distillations‚ such as wine for brandy and beer for whisky‚ are usually weak alcoholic solutions (5%-7% v/v ethanol) This seems counter intuitive

    Discussion/Conclusion In this experiment‚ t-pentyl chloride was synthesis by reacting concentrated hydrochloric acid using nucleophilic substitution sn1. In the substitution reaction the Hydrogen in HCl protonated the alcohol group in t-pentyl alcohol and turned it to a good leaving group (H2O). a tertiary carbon cation was formed. a nucleophilic attach of the negative Cl- attacked the carbon cation forming t-pentyl chloride [7]. As the reaction proceeded‚ extraction and distillation techniques were used to get a pure

    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

    EXPERIMENT 2: BATCH DISTILLATION AT CONSTANT REFLUX OBJECTIVE: To operate a batch distillation unit at constant reflux. To examine the change in top and bottom composition over time in a batch distillation. PROCEDURES: 1. Perform the general start-up procedures (Section 4). Refer appendix 1. 2. Record initial volume and refractive index of the liquid mixture in the reboiler. 3. Set the heater power to 1.5kW. 4. Set reflux timer to 10 second for set 1 and 30 second for set 2. ( Note: Set 1:

    Every step in this experiment has reasons behind its application. One determines the masses of the crucible and barium chloride hydrate for obvious data collection and calculation purposed. The heating of the sample slowly for 10 minutes is done to remove the water from the sample. A constant mass for the sample must be obtained so therefore it must be done slowly because if not you may loose mass from the sample. At the point where the crystalline solid changes to a powdery solid the sample must

    ISE: The Determination of Chloride Unknown: #34 I. Purpose: In experiment V‚ “ISE: The Determination of Chloride”‚ the concentration of an Unknown Chloride solution‚ and the Wt% of NaCl in a sample of celery salt‚ were both determined. To determine the concentration of an Unknown Chloride solution‚ a Calibration plot is first prepared. The Calibration plot is made by first measuring a series of known concentrations of Cl- (with the same activity of the unknown solution) and obtaining

    Introduction This lab proposed the question of what happens when copper chloride and iron are combined and what is the balanced equation.By completing this lab‚ the goal was to determine the equation and product for the reaction of iron (Fe) and copper chloride (CuCl2). It was predicted either solid iron or solid copper would form. Methods To begin‚ 6.00026 grams of copper chloride was dissolved in 50ml of distilled water in order to have a solution with charged iron and chlorine atoms. Then‚ 6
