Mass Spectrometry

This process is an instrumental method in which a sample is changed to fast moving positive ions by electron bombardment. The charged particles vary due to their different mass to charge ratio and are estimated with the help of this difference. It is also called mass spectroscopy.

Question

Under the conditions of this extractive procedure, how does aspirin become partitioned into the aqueous layer? How
do we then recover this substance in a pure form from the aqueous layer?
O 1) The acidic hydrogen in the carboxyl group (-COOH) of aspirin undergoes an acid-base reaction
with NaOH to form the conjugate base, sodium 2-acetoxybenzoate.
U 2) This ionic species then readily dissolves in water.
3) Conversely, the organic unknown does not possess an acidic residue, so no acid/base reaction can
occur.
4) It therefore does dissolve in water.

The amino acids alanine (MW = 89.1 g/mol) and leucine (MW = 131.2 g/mol) have solubilities of water at room temperature that are reported to be 166 g/L and 24 g/L respectively. Calculate the molar solubilities of each of these compounds. Write the structure for each amino acid and explain the trend in molar solubility in terms of the structure of the two amino acids. Do you think that leucine would have the same or a different structure depending upon if it was dissolved in water or an organic solvent such as dichloromethane? Provide the structure(s) that you might expect along with a brief explanation.
The name carbohydrate comes from the fact that many simple sugars have chemical formulae that look like water has simply been added to carbon. (The suffix hydrate from the Greek word hydor ("water") means "compound formed by the addition of water.") The actual chemical structure of carbohydrates doesn't look anything like water molecules bonded to carbon atoms (see sketch at right). But it is nevertheless possible to chemically extract all the hydrogen and oxygen from many simple carbohydrates as water, leaving only carbon behind. If you search the Internet for "reaction of sulfuric acid and sugar" you will find some impressive videos of this. Suppose you had 300.g of ordinary table sugar, which chemists call sucrose, and which has the chemical formula C12H22O11 . Calculate the maximum mass of water you could theoretically extract. Be sure your answer has a unit symbol, and round it to the correct number of significant digits.
