Separations of Mixture of Solids

The Purpose: To learn about the separation techniques that are based on the chemical properties of a substance. Observe the separation of the mixtures and their component substances. Learning how to compute the percentage a component makes up of the overall mix. The mixture contains iron filling, sand, benzoic acid, and table salt. From the visual observation of the mixture, it looks like it has a large amount of benzoic acid crystals compared to the others.

Procedure:
For this experiment, I used paper cups, 50 mL beaker, burner, the stand, weighted scale, magnet, and the mixture of solids to separate sand, salt, iron and benzoic acid. The materials that were necessary for this experiment were included in …show more content…

From the solid mixture, the iron filling was separated by using the property of iron fillings that they were attached together. The solid mixture was then spread over the surface of a sheet of white paper, then the magnet was covered with another sheet of paper and moved closely over the solid mixture. Then iron filling was then attached to the magnet and was separated and gathered in the weighing dish. The same procedure was done three times, to separate any remaining iron fillings. When the procedure was performed three times, the collected iron fillings mass was them discovered by used the digital scale. After I removed the iron filling, the sand was removed by using the property of sand that the sand was totally insoluble in the waste. The iron free solid mixture was dissolved in the solution, and was mixed with the benzoic acid along with the salt and that allowed it to dissolve was enhanced by the heating of the solution. The solution was the sent to another beaker. The leftover sand was rinsed out with a few millimeters of hot water about three times to remove any leftover salt and benzoic acid. The sand itself was dry and the mass of the sand was measured by using the dish. The benzoic acid and salt solution was …show more content…

With the magnet they were separated quite easily. When almost boiling the sand, salt and benzoic acid, it didn’t seem like I was doing the right things. I could see the remnants of the benzoic acid floating inside the beaker. It seemed like they were separated just fine, but not necessarily dissolved. When doing the filtration part, the paper also was hard, because the crystals from the ben, acid were already forming making it quite difficult to get everything out of the cup. It took me some time for the salt to
