| Titration is used to find
the concentration of a substance in solution.
It involves adding a standard reagent of
known concentration in carefully measured
amounts until a clearly defined reaction
is observed. This may be a color change,
a change in electrical resistance etc.
For example the solution being tested may
contain an unknown amount of acid. It would
be titrated with a base of known concentration
until he neutral point is reached. This
point would be determined from the color
change of an indicator.
