and
emission of the
electromagnetic
radiation (light) of its
molecules. Colorimetric
analysis is based on the
principle that many
substances react with
each other and form a
colour which can
indicate the
concentration of the
substance to be
measured. When a
substance is exposed to
a beam of light of
intensity I0
a portion of the
radiation is absorbed by
the substance's
molecules, and a
radiation of intensity I
lower than I0
is emitted.
