Morphology

impure = pure (transparent) = im + pure

The physical/chemical sense is the negative of 'pure' formed with the productive prefix 'im-', so its meaning is directly inferable.

Etymology

Impure comes from the prefix in- meaning 'not' and the root pure meaning 'clean' or 'only one thing', like 'pure gold'. So, impure describes things that are 'not pure' because they are mixed with other, unwanted substances.
