Suppose you were given a mixture of n-octane, sodium iodide and water to separate. Using the information gathered for these and similar compounds in this experiment, and using what you know about the properties of these materials from other contexts, outline a procedure that could be used to do a quantitative separation of these three materials. Your procedure should be specific enough, that if followed, someone could determine the amount (mass) of each of the three materials present in the...

Question 2,3,4 please.
ESTIONS: 1. Many students do not recover 100% of the original mixture. Describe at least two possible problems that could cause less than 100% recovery of the mixture. 2. A student received a mixture that actually contained 50.0% salt and 50.0% sand. At the end of the experiment, this student calculated that his sample was composed of 45.2% salt and 54.8% sand. What might he have done (or not done correctly) during the experiment to cause this...

Organic Chemistry Nitration lab. 1. Aromatic nitration requires the use of the HNO3 / H2SO4 mixture. Why not use HNO3 alone? 2. Why should the cold nitration reaction be maintained at all times? 3. What difference should be observed between the 1 H NMR spectrum of the nitrated reagent and the product obtained? Explain 4. If the yield percentages for acetanilide nitration products were: 35% o-nitroacetanilide and 65% p-nitroacetanilide, explain how you would perform the procedure to separate and recover...

Post-lab Filtration experiment questions. 1. If your goal is to separate oil from sand, estimate how much of oil and how much of the sand do you lose during the vacuum filtration experiment. 2. How would you modify the experiment procedure, if I would give you a mixture on unknown amount of oil and sand and would ask to calculate the weight percentage of sand in the mixture?
