Vapor pressure is not a linear function of temperature, but instead has a more complicated logarithmic relationship. A homogenous mixture (i.e., a solution) of two liquids boils when the vapor pressure of the mixture is equal to the applied pressure, that is, when the sum of the partial pressures of the components (PA, PB, PC .) equals the applied pressure, Ptotal. Thus, at the boiling point [Ptotal = PA + PB + PC]. In this experiment, simple distillation [Part 1] will be compared to fractional distillation [Part 2]. Lecture Ideas Explain bumping and the boiling chip Boiling chip have fissures that enables gas to collect without a violent eruption. Discuss vapor pressure Solids, like salt, have almost no vapor pressure. All liquids have a vapor pressure, a temperature dependent equilibrium proportional to the forces required to keep a substance in its liquid st ...

My group was responsible for simple distillation . Simple distillation apparatus was set up as noted in the manual. A round bottom distilling flask containing 25 mL mixture of methanol and water was connected to the distillation head. And a thermometer was inserted to the tip of the distillation head. The mouth of the flask was held by clamp. Small amount of grease was applied to where apparatuses joined. Right under flask, the heating mantle was placed. Condenser, which two hoses were connected for water in/out, got connected to the distillation head. Instead of using a round bottom receiving flask, a graduated cylinder was used. In order to prevent condenser from heating up, water was turned on and flowed into the condenser through the water inlet. Heating mantle started to apply heat to the round flask. The rheostat for the heating pad was set at 4 for initial temperature. Diagram of Ap ...

How to Write a Discussion and Conclusion Step 1: Ask yourself a series of questions You should be able to come up with about 20-25 questions about a given experiment. The best time to ask the question is during the experiment. When you think of it, just write it down. You do not need to answer it right away, but it should be written down because you will probably forget it later, and by writing it down, you can get a clearer picture of the question. Some examples for the distillation experiment are as follows: 1. 2. 3. 4. 5. 6. What is a distillation? Why did I have to insulate the column? Why was the stirbar important? What is a simple distillation as compared to a fractional distillation? When do you use a simple or a fractional distillation? What role does surface area play in fractional distillation? Step 2: Eliminate those questions that are not important Go through all of your questions and remove those that you do not need to worry about. This elimination process is done by going through your notes ...

Be advised that the filter paper may clog in spite of this procedure. If a small amount of your crude product refuses to go through the filter paper, stop the aspirator flow and continue with the filtrate that you have. If a large amount (>50 mL) remains unfiltered, you and your partner may set up a second Celite filter. Discard the yeast residue and the celite in the trashcan. Combine the filtrate with the decanted material. Swirl to ensure a homogenous mixture. Then place approximately half of the mixture in a 500 mL round-bottomed flask for each student to use for distillation. One student should assemble a simple distillation apparatus (Zubric Fig. 20.1, p. 166). The other student should assemble a fractional distillation apparatus (Zubrick Fig. 20.10, p. 180).

The temperature at which boiling occurs is generally measured during the distillation of a liquid and is a characteristic of the pure compound. Thus, the boiling point is an important physical characteristic that can be used in determining if liquid compounds are the same or different. You will use a standard-scale simple distillation to purify your assigned liquid and determine its bp. A description of a simple distillation apparatus and an outline of a simple distillation procedure are presented in Padais pp. 131 and the procedure is outlined below. Prepare your laboratory notebook for Experiment 1 as described on pp. 16-18 of the lab manual. The following procedure must be written in your notebook as you work in the laboratory. Specific Instructions for Bp Determination 1. Assemble the simple distillation apparatus (See model apparatus on the front bench in the lab) being careful to properly position the thermometer bulb.

	distillation lab McGill, CHEM 212 Excerpt: ... CHEM212: Organic Chemistry 1 DISTILLATION V.P.C. Experiment #3 Introduction: The aim of this experiment was to determine the molar composition of a mixture of methanol and butanol, using simple distillation , fractional distillation, and vapor phase chromatography. Results and Calculations: Graph 1: Distillation curve for the simple distillation of methanol-butanol According to the distillation curve above, a 20.0ml sample of methanol-butanol should contain approximately 6.5ml of methanol and 13.5ml of butanol. Calculations: # of moles of methanol = (6.5ml x 0.79g/ml)/32 = 0.160 Mole fraction of methanol (Nm) = nm/ (nm+nb) = 0.160/0.308 = 0.519 # of moles of butanol = (13.5ml x 0.81g/ml)/74 = 0.148 Mole fraction of butanol (Nb) = nb/ (nm+nb) = 0.148/0.308 = 0.481 Therefore the volume composition of the mixture from the above graph is 52% methanol and 48% butanol.
