A chemistry technique
used to find out the concentration
of a substance (or concentrations of substances) by slowly putting in a known
amount of another substance which can neutralize
the effects of the unknown
A pH-sensitive color indicator (which reacts with neither substance) is also included; the color of the solution changes when all of the unknown substance has been neutralized. The unknown is then inferred by looking at the total amount of known substance it took to neutralize all of it.
