titration
)
A method used to find the concentration of an acid or an alkali. Typically a burette is filled with an acid of unknown concentration which is slowly (drop by drop) added to a known volume of an alkali of a known concentration, mixed with an indicator (such as phenolphthalein). The volume of acid need to neutralize the alkali in the flask can be used to calculate the concentration of the acid.
In analytical chemistry, a technique to find the concentration of one compound in a solution by determining how much of it will react with a known amount of another compound in solution.
One of the solutions is measured by pipette into the reaction vessel. The other is added a little at a time from a burette. The end-point of the reaction is determined with an indicator or an electrochemical device.
