5. Suppose you are trying to separate butanoic acid and 4-iodotoluene via extraction with diethyl ether and water. (a) Look up the structures and draw them below. Predict which reagent would have a greater preference/affinity for the diethyl ether layer (1 pt) (b) Which solvent will be on the bottom in the separatory funnel (or conical vial) (1 pt)? (c) U to the butanoic acid and which layer would it prefer- aqueous or o pon treatment of butanoic acid with...

()UESTIONS 1. If you had used a different mass of magnesium metal, would you expect the empirical formula of the compound to be the same? Explain. 2. If you had omitted steps 12 and 13 from the experiment, how would this omission have affected your results in terms of the empirical formula of the magnesium oxide? In other words, would the ratio of the magnesium to the oxygen have been greater or less than the obtained ratio? 3. From the...

3) Combination Reaction Mg + 02 Mgo Procedure: Obtain a small piece of magnesium metal and note the appearance of the metal before heating. Use the tongs to hold the piece of magnesium metal and place the strip in the hottest part of the burner flame to ignite the metal. (Note: If you have already done this reaction this semester, you do not have to repeat the reaction, but you do need to complete the questions in the report.) DO...

From You have a mixture of benzoic acid, hexamethylenediamine, and 1-octanol dissolved in diethyl ether. You wish (for some reason) to separate these compounds and have pure samples of each. Devise a liquid-liquid extraction protocol that would allow you to do this. (up to 20 points) Your answer should be clear and concise. Ambiguous answers or those that are difficult to read will NOT receive points. Search entries or author Unread Subscribe Reply

3. A crude nonacidic product mixture dissolved in diethyl ether contains acetic acid. Describe an extraction procedure that could be used to remove the acetic acid. b. When the two layers form during an ether/water extraction, what would be an easy, convenient way to tell which layer is which if the densities were not available.

HCL in sep funnel. Collected.
Now:
1) You added NaOH to organic phase collected in problem 2 to
extract another compound,
Which compound was extracted in NaOH solution? Justify with
chemical equation
2) to the aqueous phase you added HCL solution until it’s ph
was less than 7. What happens if it’s ph is 7 or above?
3) when you acidified the solution by adding HCL, a white
precipitate was produced....
