change separation Lab I am one of the chemists assigned to design a cost effective procedure for use the separation and recovery and hazardous barbaric disposal. The difficulties were trying to figure out Is how we spate effectively separate Carbons, sense, and naphthalene? The speculation we chose to act upon this problem was If we put the form into piss, alcohol, and mineral life, then in each radical one or more subject matter will not dissolve, will be visible, and also able to separate.According to our entropy our hypothesis supported the experiment because and sand atomic number 18 lobule in water while naphthalene is not. The CARBONS, and sand will dissolve in the limpid solvent and the naphthalene will remain in the solid phase. In the other inwardnesss methyl alcohol and mineral spirit were not dissolvable in both Carbons and sand. withal in naphthalene mineral spirit was not oil- meltable. To follow out this experiment we did the following as to compor t a successful hypothesis.First use lead separate ml testify tube, and added ml of each substance Including water, methanol, and mineral split. If the Carbons Is something that Is water soluble, then water can be added to the mixture and then It can be altered as the sand is non-water-soluble and will be left behind. Also add 0. 20 grams of each mixture including Carbons, naphthalene, and sand to each test tube. endeavor to stir or shake the substance to dissolve.If that didnt work to dissolve the mixture we make a filter paper and hardened it in a funnel then try to filter it by displace the savor in. later that this leads us on to the third option of separation which is evaporation. At last we located our sample test in an Erlenmeyer flask and then placed it on a hot bob up with melting point 8. 2 0 c, waited to evaporate then recorded our data. After each test, try to observe If the sample was soluble In any of the substance.My data definitely supported my hypothesis bec ause In that experience we found out In the lab that H2O was not soluble In naphthalene, and sand. Methanol was not soluble in Carbons, and sand. Also mineral spirit was not soluble in in all the substances. Some errors that big businessman have alter my experiment was the evaporation state I think we left it a pocket-size bit too long or took it our earlier for the solution. In the filtering stage we might have spilled some of the sample solution so hats why we maybe got contrasting result.
