redox titration

[′rē‚däks tī′trā·shən]
(analytical chemistry)
A titration characterized by the transfer of electrons from one substance to another (from the reductant to the oxidant) with the end point determined colorimetrically or potentiometrically.

Among the experiments are determining the formula of a copper supplement, the spectroscopic determination of food dye in popsicles, using an appropriate indicator for acid-base titrations, determining the amount of ascorbic acid in a vitamin C tablet by redox titration, and analyzing biodiesel synthesized from canola oil.
Summary: The aim of this study was to investigate the levels of ascorbic acid (vitamin C) in various plant samples, which were available in Iran markets, by redox titration method, using2,6- dichlorophenolindophenol.

Among different methods for measurement of vitamin C, such as electrophoresis [4], chromatography [5], voltammetry [2], biamperometry [6], spectrophotometry [7], high-performance liquid chromatography [8] and titration by iodine [9], the simple redox titration of AA by 2,6-dichlorophenolindophenol (DCPIP) is accepted as a standard method for determination of vitamin C [9, 10].
Keywords: arsenic trioxide; potassium bromate; redox titration.
The method chosen here to assay the potassium bromate is the redox titration of bromate with arsenious oxide in acid medium (8,9,10), because of the availability of the primary standard, SRM 83d, Arsenic Trioxide Redu ctometric Standard, and the simplicity of the reaction.
The assay procedure [8,9,10] was a redox titration in which [As.
Specific techniques are then covered, with an introductory chapter to each family of techniques-- including acid/base & redox titrations, electrochemistry, spectrometry/spectroscopy, chromatography, and kinetics --and then specific procedural and mathematical guidance.
We have started to investigate possible replacements for this chemical in some uses in undergraduate labs involving redox titrations.
TL Easy, available from Gerhardt UK, is an accurate, self-contained programmable titration unit which is suitable for pH and redox titrations, for both sugars and salts the redox mode is used.
