titration


titration
Volumetric analysis by means of the addition of definite amounts of a test solution to a solution of the substance being assayed. [Fr. titre, standard]
- colorimetric t. a t. in which the end point is marked by a color change.
- formol t. a method of titrating the amino groups of amino acid s, by adding formaldehyde to the neutral solution; the formaldehyde reacts with the NH3+ group, liberating an equivalent quantity of H+, which may then be estimated by t. with NaOH.
- potentiometric t. a t. during which the pH is continually measured with some value of the pH serving as end point.

ti·tra·tion tī-'trā-shən n a method or the process of determining the concentration of a dissolved substance in terms of the smallest amount of a reagent of known concentration required to bring about a given effect in reaction with a known volume of the test solution esp the analytical process of successively adding from a burette measured amounts of a reagent to a known volume of a sample in solution or a known weight of a sample until a desired end point (as a color change) is reached

ti·tra·tion (ti-traґshən) [Fr. titre standard] determination of a given component in solution by addition of a liquid reagent of known strength until a given endpoint (e.g., change in color) is reached.
