    Rey Vincent P. Antonio Experiment 8: Quantitative Determination of Copper Concentration in Aqueous Solution by Iodometric Titration Results and Discussion Oxidation-reduction titration is a kind of volumetric analysis where the titrant used undergoes a redox reaction with the analyte. In this experiment‚ the oxidation of iodide (I-) to produce iodine (I2) is taken into consideration. The use of this concept in a redox titration is called iodometry. Iodimetry‚ on the other hand‚ deals with the
