CHM120H5 Lecture Notes - Lecture 7: Stoichiometry, Redox Titration, Bromate
Document Summary
Determination of the product of a redox reaction: reaction of bromate and. Titration is a key method of chemistry that can be used in many different ways to help uncover unknown amounts of products. One way titration is used is to determine the presence of. This helps to establish the nutrition values that certain juices have or lack. The process includes using iodine and iodate solution in a redox titration with a starch indicator acting as the endpoint of the titration1. This goal was accomplished by using a known excess amount of bromate and a known amount of hydroxylammonium. Hydroxylammonium acted as the limiting reagent while the. Bromate reacted with potassium iodide solution. (2) bro3. + 9i- + 6h3o+ br- + 3i3. The rest of the iodine was titrated with thiosulphate until an endpoint was reached as indicated by the starch indicator. Knowing the amount of bromate initially and the excess, the reacted bromate could then be calculated. (3) i3.
