9 Set up an apparatus for evaporating the,water as shown in Figure 3. 1 Mass of the original mixture,2 Mass of salt recovered. 3 Mass of sand recovered,4 Percentage of salt in the original. 5 Percentage of sand in the original,6 Percent error Section 3 1 in text. Figure 3 Evaporation apparatus,Wilbraham Staley Matta 1995 p 18.
10 Light the burner and slide it under the,beaker Establish a gentle boil and avoid. spattering Remove the burner from 1 Calculate the sum of the percentages. under the beaker if boiling becomes of sand and salt from above In terms. vigorous or salt spatters Ensure that the of conservation of mass explain why. salt is completely dry before turning off the ideal total should be 100. the burner Alternate drying method, Use a heat lamp or drying oven 2 What procedural event would lead to. overnight a sum of less than 100 More than,11 Mass the beaker and the dry salt when. the beaker is cool to the touch 3 Identify one mixture one solution. and one compound from the lab, 12 Rinse the beaker in the sink Clean Create a table or chart that identifies. dry and put away all lab equipment the characteristics that distinguish. these different types of matter,13 After the sand and filter paper are dry.
obtain mass Dispose of the filter paper 4 Crude oil is separated or refined. and sand as directed into simpler components using a. technique called fractional,distillation Using your textbook or. internet resources locate a diagram,or moving animation that explains. 2 Mass dry filter paper g this process What physical property. allows this separation to occur, 3 Mass container with sand salt g Using the diagram animation briefly. describe the process from start to,4 Mass empty container g finish. 6 Mass clean dry 250 mL beaker g,5 Alkanes are molecules containing.
11 Mass beaker with dry salt g carbon and hydrogen with the carbon. atoms joined one after another in a, 13 Mass of dry filter paper and sand g chain Crude oil is composed. primarily of a mixture of alkanes,Examine the table below. Central Bucks Chemistry Laboratory Manual 2 1 Physical Separation Lab. Table 1 Alkane boiling point data Table 2 Separation lab data. American Chemical Society 2002 p 182,Complete Discussion Conclusions. 3 Application Questions, Make a graph of boiling point vs Table 3 and 4 show data collected in two. number of carbon atoms and use the different trials of the same lab. graph to predict the boiling point of, the alkane with 11 carbons Table 3 Separation lab data Trial 1.
