Mixture Lab Write Up

judicial separation of a brininess, Sand, and Water Mixture Jamie Schurz and capital of Texas Hoggard Date experiment was per varietyed September 6 and September 7 Int celestial poleuction utilization The purpose of the experiment was to use discordant lab equipment and lab techniques to separate a miscellanea of brininess, common sense, and wet. Background An element is the simplest form of a substance that retains the properties of that substance. A involved is a substance formed by combining 2 or much elements set in fixed proportions. A mixture is a system of two or more distinct chemical substance substances. Unlike compounds, mixtures can be naturally combined.Because the components are physically combined, they can in addition be disordered victimisation physical properties. Physical properties are properties that do non change the chemical nature of matter. In this lab, a mixture of common season and mainstay will be separated using the listed equip ment and separation techniques. Hypothesis If a mixture of gritstone (3. 3g), flavor (1. 2g), and body of water is separated using filtration and huming lodge, hence close to of the gritstone and salt will be cured. Safety Information During the experiment, leave sentry duty wear should be worn at all times such as goggles and an apron (to prevent salt or heated water from entree the eye).Beaker tongs should be apply to comp allowe the heater beaker from the appropriate heating immutability and then it should be carefully transported onto the designated touch vulcanized fiber pad to cool. Materials and Methods * * Graduated cylinder * Small beaker ( degree centigrade mL) * Large beaker (600 mL) * Hot domicile * Small ring * Funnel * dawn idea * Glass stir rod with rubber policeman * Hot mitts * Beaker tongs * Pressed fiber pad * reckon boat * Electronic balance * Scoops * Salt and sand sample * water data-based Procedure 1. Put on appropriate safety wear. 2. B egin this experiment with 47 mL of water, 1. 2 g of salt, and 3. g of sand. * Use the 100 graduated cylinder to find the 47 mL of water, recitation from the meniscus. * Put the weigh boat onto the electronic balance and zero it out, then slow add the salt until you have 1. 2 grams of it. Do the same for the sand. * Also bus the larger of the two beakers 3. Combine the 1. 2g of salt and 47 mL of water into the 100 mL beaker and stir until the salt is fade out 4. Add the sand and wait until it settles onto the bum of the beaker. 5. flowerpot the filter report and then fold it into a small cone. laden sides before placing into funnel that is inside a ring stand.Place larger beaker underneath funnel. 6. soft pour sand and salt mixture by dint of filter paper. Let the sand dry. 7. Take large beaker with salt and water and place on top of a calefactory place. Set hot plate onto its highest setting and let boil. 8. Once salt starts popping lower temperature on hot plate. When closely of the water has evaporated remove from hot plate using beaker tongs and let rest on pressed fiber pad. 9. Turn hot plate off. 10. Mass out recovered sand and salt. Results stark naked Data object Mass (g) scratch quid of salt 1. 2g Starting luck of sand 3. 3gDry filter paper 0. 7g Larger of the 2 beakers 103. 1g Total mound of beaker/salt (after) 105. 3g Mass of recovered salt 2. 2g Total surge of filter paper/sand (after) 4. 1g Mass of recovered sand 3. 4g Important results * The mass of recovered salt was 2. 2g * The mass of recovered sand was 3. 4g * The percentage misunderstanding for the mass of recovered salt was 83% error * The percent error for the mass of the recovered sand was 3% * The percent yield for the mass of the recovered salt was 183% * The percent yield for the mass of the recovered sand was 103% CalculationsDiscussion judge results v. Actual results In the experiment, the mass of the salt recovered was larger than the mass of the metre of salt that was started out with. This may be due to the tap water that was used not being pure or that some sand was small rich to not be filtered out. Analyze experimental error During the experiment, sooner of measuring the water out to exactly 47mL, around 60 mL of water was used. This could have caused on that point to be extra water during the nett measurement.There was not enough time to boil off the extra water this was through with(p) by another person ulterior without either partner in the gathering supervising. Also, when looking for the sand sample the close day, it was missing so another aggroups sand data was massed instead Improvements Having a longer time to demeanour the experiment might have changed the data. sort of of leaving the sand sample in the open on a turn off to all classes, it may have been infract for them to be separated more. Results in monetary value of the purpose The aspiration was to get most of the salt and sand back through filtration a nd evaporation.Most of the sand was recovered however on that point was a great deal of added mass to the salt (around 1g). The goal was met as farther as data is concerned. Conclusion The goal of the experiment was to see if using boing point and filtration could recover close to the same amount of money of salt and sand put unitedly in a mixture. The experiment revealed a percent yield of 183% for salt and 103% for sand, which does behave the hypothesis that using those two techniques, most the same amount of salt and sand would be recovered.
