Separation of a Mixture of Solids
Lab #2 – Separation of a Mixture of Solids

Abstract
The mixed solution contained benzoic 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. Benzoic 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 solution. 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 benzoic 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 benzoic 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 filings 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 benzoic acid are completely removed from the sand. An ice bed was necessary to observe the benzoic acid crystallizing. The ice bed allowed the burning benzoic 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 benzoic acid, filtration was used. The mass of the filter paper was 1.1 grams. The ice bath was

    Procedure: I started off by removing the iron using the magnet, and then I weighed all of the iron I obtained from the mixture in a container I already knew the weight of and calculated the net weight of the iron. Next, I took the remaining contents of the mixture and added it with 50 mL of distilled water in the 100 mL beaker, heated it up to separate the sodium chloride and benzoic acid from the insoluble sand, then poured out the benzoic acid and sodium chloride into a separate cup and allowed I to chill in an ice bath for approximately five minutes. I dried up the sand and calculated the net weight for that. I poured the benzoic acid and sodium chloride mixture into a filtered funnel that caught the majority of the benzoic acid and allowed the sodium chloride to drain through to the cup. I allowed the two separate components to dry up and let the water evaporate and then weighed them out and obtained a net weight for the two of them as well as a mixture percentage for all four components.…

    In this Laboratory experiment, my lab partner Alexander and I were able to understand thoroughly the physical and chemical properties of salt (NaCl) and sand (SiO2). Followed by the right procedure we were able to design and test out the components of both NaCl and SiO2 in order to separate the unknown mixture that we were able to find out about. We were also given the task to provide the percent composition of the mixtures. Therefore, the separation of components among this experiment allowed us to obtain the right numbers for our calculations.…

    I figured filtration was the method would be the procedure used for removing the sand. I did not know how the benzoic acid would be removed, I did however think that distillation would be used to remove the salt. The method of boiling and dissolving the salt and benzoic acid from the sand was surprising. I didn’t expect the sand to stay at the bottom when I poured those elements into a different container.…

    At first the technique of filtration to filter the sand from the salt water is used. Filtration is a procedure that separates a heterogenous mixture, with the use of filtration paper. Then the mass of the sand will be found using a balance. A balance is an instrument that finds the mass of an object. Evaporation is then used to separate the homogenous salt water mixture. The salt will be separated from the water through evaporation. Evaporation is a separating technique that uses some form of heat to evaporate a liquid leaving behind any substance not chemically bonded to the H2O. Also, an oven will be used to get rid of leftover moisture in the sand.…

    This experiment was started with a clear solution of sodium benzoate and HCl was added to it, ultimately producing benzoic acid. First, .3395 g of sodium benzoate was weighed, then it was dissolved in water, causing it to disassociate into ions. Next, 3M of HCl were added drop wise to the solution until it reached a pH of 2, thus introducing the hydronium ion. This addition caused a white, solid benzoic acid to precipitate out of the solution. A vacuum filtration system was used to separate the solid from the liquid. What was once water soluable became insoluable.…

    Therefore we were able to separate the parts with simple methods. Separating the largest part of the mixture with a strainer was the easiest of the procedures. The iron filings are magnetic so using a magnet, with several passes, produced all the filings. Salt is water soluble, so mixing it with water and using a filter to strain the salt water from the larger sand particles was preferred. The method used by group 1 produced the results closest to the original weight. The method used was the most precise as compared to all other instances. The results over all groups were either over or under initial weight. To receive closer measurements a better salt wash to separate salt from sand would give more accurate results. Also a better straining method that doesn’t absorb some of the salt solution and trap sand would give more exact measurements of the individual components of the…

    To begin this experiment I got out me scale and little plastic dish and the mixture of substances. I weighed the dish separate and found it to weigh 0.5g. Next I added the mixture to my dish and found the combined weight of the dish and the mixture was 5.5g. I next cut a square sheet of paper and weighed it to find it weighed 1g. I emptied the contents of my dish onto another sheet of paper in a very thin layer. I wrapped the magnet in a sandwich bag and ran it over the mixture to separate the iron. I then carefully pulled the magnet away from the sandwich bag and let the iron fall onto the square piece of paper. I repeated this 3 times to ensure I had all of the iron from my sample. I then weighed the square piece of paper and iron shavings and got a weight of 2.2g. I discarded the iron and moved the remaining mixture into the glass beaker. I added 50mL of distilled water to the mixture. I then lit my burner and moved the stand over the flame and set the beaker with the mixture over the flame. I stirred the mixture several time and when I began to see small bubbles forming I poured the liquid into a paper cup. I then added 20mL of distilled water back into the beaker with the now sand and repeated setting it over the flame until a near boil. I then added this water to the other water in the paper cup and set the sand in the beaker over the…

    The masses for the benzoic acid, 4- chloroaniline and naphthalene are as follow 2.890 g, 3.024 g and 3.036 g. The masses for the three products demonstrates that there was almost an equal amount of product that was extracted for each compound. The beginning mixture was 3.5 g which had equal amounts of the three compounds. Because the masses were close in range and they yield an average of 84.8 % percent recovery the experiment proved to be an effective technique of separating an organic acid, a base and a neutral compound. There could have been possible sources of error that occurred during the extraction process of the compounds because the percent recoveries were less than 100 %. Some possible reasons for a lower percent recovery are not properly drawing off the lower layers and extracting part of the top layer or leaving excess precipitate in the vacuum filter. Once the products were collected and weighed the melting point of each compound was recorded. The melting points for the acid, base and neutral compound are 100ºC, 81ºC and 75ºC. The melting point results are somewhat consistent with the literature values because the benzoic acid was lower than 122ºC while the 4-chloroaniline was within the range of 68-71ºC and the naphthalene was 5ºC lower than the expected melting point of 80ºC. A possible reason for the inconsistencies are the point at which the product turned to liquid was probably not properly…

    Procedure: I began this experiment by using a magnet to pick up and collect the iron filings out of the mixture. Then the sand was separated by placing the mixture into a beaker and boiling it in distilled water in order to dissolve the salt and benzoic acid, once boiling the liquid was poured out leaving the sand behind; which was then heated until dry. The next step was to use filter paper to separate the benzoic acid from the salt. Once the liquid was poured through the filter paper it was set aside to allow the benzoic acid to cool. The final step was separating the salt, which was done by allowing the cup containing the filtered solution to set out until the excess water had evaporated and only the salt was remaining.…
