Question

The top of the separation scheme shows what other compound is mixed with your molecule(the one on the left). Assume for the purposes of this assignment that both compounds are solid at room temperature. Assume that both compounds are soluble in ether, except ionic compounds. The goal of the separation is the isolate each of the two compounds from the mixture.

o Below the incorrect separation scheme write a discussion of this incorrect scheme identifying all of the mistakes in the separation scheme. Keep in mind that there will be more than one mistake in the scheme.

o For each mistake, give a detailed, scientific explanation of why it is incorrect.

Then, draw a correct separation scheme. Make sure to indicate the phase of each chemical in every step (s, l, g, aq) and write the separation technique used in each step (ie: vacuum filtration).

You can use any of these in separation scheme:

10% aqueous NaOH	 H2O
 5% aqueous NaHCO3	 H3PO4
 6M HCl	 anhydrous Na2SO4
 5% HCl	 anhydrous MgSO4
 Diethyl ether (ether)	 Saturated NaCl
 CH3OH	 Sodium borohydride (NaBH4)
 lithium aluminum hydride (LiAlH4)	 NaCl solid
