20.
Of the compounds in the exercise above, salts would be mostly easily formed
with the ones lettered ___, ___, and ___. The two classes of organic
compounds which will form salts when reacted with inorganic bases are
_________ and ___________ __________. The class of organic compounds
which will form salts when reacted with inorganic acids is _________. This
property of carboxylic acids and amines is most useful in pharmacy because it
helps to make organic compounds that are very ________________ in water.
Such salts tend to be quite soluble even when the molecular weight is high.
They can thus be more easily utilized by the body.

In organic chemistry, a molecule is oxidized if it (gains) (loses) oxygen atoms or
if it (gains) (loses) hydrogen atoms. Reduction is the opposite of oxidation. In
organic chemistry, a molecule is reduced if it (gains) (loses) oxygen atoms or
