Separation of a Mixture of Solids Essay
The mixed solution contained benzene acid, iron, table salt, and sand. When separated using water, fuel, or a magnet, their characteristics and properties changed. The mass of the entire mixed solids was 6. 6 grams. When the magnet was used, the iron was immediately picked up. The mass for that was 1. 7 grams. The table salt was 1. 2 grams. Benzene acid mass was 0. 8 grams and the sand was 1. 4 grams after being separated. Introduction The objective of this lab was to separate and examine different solutions within a elution.
In order to separate each element different methods and techniques were used. Separating the Iron filings wasn’t difficult or lengthy; however It did require patience and a steady hand. Separating the benzene acid and the table salt took the longest because it needed to air dry causing the water to evaporate. Methods While the water was boiling with the table salt, sand, and benzene acid, the water got thick. It was difficult to separate the solids because they would get stuck to the bottom of the Styrofoam cup.
In order to separate the iron flings a magnet was used. The solution first needed to be spread out on a piece of paper. As the magnet was ran over the solution, the iron filings were picked up. It took several tries to get all of the iron picked up. To separate the sand, the burner and distilled water was used. As it boiled, it had to be stirred to make sure it was completely dissolved. Having done this twice ensures that the salt and the benzene acid are completely removed from the sand. An Ice bed was necessary to observe the benzene acid crystallizing.
The Ice deed allowed the burning benzene acid to cool down and change appearance and texture. The sand had to be over low heat to be completely dry. No sand splattered which made it effective for the data. To separate the benzene acid, filtration was used. The mass of the filter paper was 1. 1 grams. The ice bath was used again to chill the distilled water in the cylinder. The table salt and benzene crystals were poured into the funnel filter paper. This had to be left to air dry overnight. To separate the sand, the Styrofoam cup had to also be left aside overnight for It to be completely dry.
Results After each solid was separated, they were able to be weighted. The solids weighted were iron filings, sand, table salt, and benzene acid. Data Table: Experiment Data Grams Percent of mixture Iron flings 33. 3% Sand 1. 4 27% Table salt 1. 2 23. 5% Benzene acid 0. 8 15. 7% Total 5. 1 99. 5% Discussion This lab concluded that properties are contributory when it comes to separating solids. Using the magnet to gather all the iron filings was very effective, though it did take several tries. Solubility played a huge part in this lab.
Each solid took a different amount of time and a different method to become separated due to solubility. This lab did bring up a few questions. For example, would the mass of the table salt or the benzene acid be different if it was boiled rather than air dried? What would happen if the sand was actually air dried rather than boiled? I wonder if their properties would have changed as well. The disadvantage with my data table is the totals. It does not equal 100, though it is very close. Solubility was definitely key in this lab.
