- 30 20 10 From the procedure 2. Assemble the simple distillation apparatus as generally shown in Figure SD.1 in the lab manual, ensuring that the thermometer bulb is aligned at, or slightly below, the Y in the distillation head. Each ground joint is greased by putting three or four stripes of grease lengthwise around the male joint and pressing the joint firmly into the other without twisting. 3. Attach a water condenser to the distillation head. 4. Remember, water goes in the bottom and out the top. Attach a clamp holder to the end of the drain tube to keep it weighted in the drain. Turn water to a trickle. If it is slowly draining, it is high enough. Begin a low flow of water through the condenser. 5. Place the set up on a heating/stir plate. 6. Turn on the hot plate to start heating the solution. Monitor the temperature and the boiling of the solution throughout the distillation process. 7. Record the temperature of the distillate when the first drops are recovered. 30.0 8. Adjust…Simple and fractional distillationDifferentiate between simple distillation and fractional distillation. Please elaborate.
- A high concentrated solution having a volume of 100 liters is mixed by 85% alcohol and 15% gasoline. It was found out that a 50-50 percent mixture is also appropriate in the solution. How much gasoline should be added to the high concentrated solution in order to have a 50-50% mixture?Preparing solution. Weigh out Sg of table salt. Dissolve it in 50mL of distilled water in a container using a stirrer and label appropriately. Calculate the concentration in terms of percent mass per volume. If you pour the 10ml hydrochloric acid into50ml distilled water Calculate it concentration in terms of percent volume acid per total volume.1. Explain how distillation works in separating simple mixtures. 2. Differentiate simple distillation and fractional distillation. 3. What is an effective way of preventing irregular ebullition or bumping of the mixture during distillation?
- 3 ways to separate water to a liquid mixture and its step by step procedureThe distillation flask is best completely filled with mixture as large as available never less than half empty about 70% fullA pure crystalline "compound A" has a melting point 105-107 °C. If this compound is mixed with a small amount of another compound, what happens to the melting point? O It would have no effect on the melting point. It is impossible to know what would happen. O It would raise the melting point and the range would decrease. It would lower the melting point and the range would widen.
- Explain how can you use the melting point can be used to determine the purity of a substance.In chem lab when creating aspirin, how does a melting point range for pure aspirin compound differ from impure? Explain the meaning of value and range of melting point.
