The solution of known concentration is gradually added to the unknown solution from a burette (a long measuring tube with a valve at the bottom) until the equivalence point (end point) is reached. The amount of the unknown substance can then be calculated.
This method makes it possible to locate the equivalence points for ost titrations fairly accurately.
