Abstract
A method is described for oxidimetric determination of tartaric acid or tartrates with potassium cupri-3-periodate in alkaline medium. The oxidation is completed in 5 minutes at room temperature, and the unreacted reagent is retitrated with standard arsenite solution. Oxalic acid is not oxidized under these conditions. This method could be used for determination of tartaric acid in presence of other plant acids (e . g. in fruits and fruit juices) after separation accomplished by a method developed by Schenker and Rieman III, using ion exchanger Dowex 1 - X 10.
