Fractional Distillation Lab Report
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 plateaus, we found them at about 81.5 and 100.4. This graph and table show the plateaus at around 82.8, and 99.4, which is close but now the same as our first trial. We decided to go with the first time we did it because we feel it was more accurate and we weren’t busy watching the time and

At the start of the graph it is consistent for a few seconds then rapidly increases to about 80°. It remains there for a little bit then slowly goes up to the second plateau, around 99°.
Conclusion
The goal of sludge is to separate a mixture of liquids and soluble and insoluble solids and find their properties. The first thing we did was use physical means to pick out the insoluble solids with our fingers. We needed to find the density, magnetism, and malleability of the solids. We used water displacement to find the volume of each of the insoluble solids. We then found the mass of the solids, then divided the mass by the volume and found the density. Density’s- Nut- 6.9 g/cm^3, Marble- 2.06 g/cm^3, silver pellets- 0.4 g/cm^3. We tested magnetism by using a magnet, and malleability by smashing each solid with a hammer. Magnetism- Nut- yes, marble- no, Pellets- no. Malleability- Nut - yes, Marble - no, Pellets - yes. The next thing we did to separate our sludge, was distillation. We set up the distillation by putting solution in a
