The iodometric titration shows higher PV overestimations in comparison with the TPP/TPPO assay, for both hydroperoxides. An accelerated oxidation of different oils is assessed with the two methods, and the results confirm this observation since higher PV values are measured with the titration method. The TPP/TPPO assay coupled with the ATR‐FTIR spectroscopy appears as a simpler and faster ...

The iodometric method suffers interference from reducing substances that react with iodine, including thiosulfate, sulfite, and various organic compounds, both solid and dissolved. Eliminate interferences due to sulfite, thiosulfate, iodide, and many other soluble substances, but not ferrocyanide, by first precipitating ZnS, removing the supernatant, and replacing it with distilled water. Use ...

Ascorbic acid is suggested as the weighable compound for the standardization of iodine solutions in an analytical experiment in general chemistry. The experiment involves an iodometric titration in which iodine reacts with ascorbic acid, oxidizing it to dehydroascorbic acid. The redox titration endpoint is determined by the first iodine excess that is complexed with starch, giving a deep blue ...
Chemists use titration as a method of quantitative analysis; that is, the method allows the exact quantity of a compound to be determined. Fundamentally, titration involves the combination of two chemicals that react and a means of monitoring the progress of the reaction .

This titration is commonly referred to as iodometric titration. Redox Titration Example. An example of a redox titration is the titration of potassium permanganate (KMnO 4) against oxalic acid (C 2 H 2 O 4). The procedure and details of this titration are discussed below. .
Errors in Titration Experiments ... The end point of a titration is when the reaction between the two solutions has stopped. Indicators, which change color to indicate when the reaction has stopped, do not change instantly. In the case of acidbase titration, the indicator may first lighten in color before changing completely. Also, each individual perceives color slightly differently, which ...

The iodometric titration is a general method to determine the concentration of an oxidising agent solution. In an iodometric titration, a starch solution is used as an indicator since it can absorb the I² that is released. This absorption will cause the solution to change its colour from light yellow to dark blue colour when titrated with standardised thiosulphate solution indicates the end ...
