WebSep 17, 2024 · This iodine is immediately consumed by the thiosulfate ions (S 2 O 3 2-) in a pathway described by reaction (6). As soon as all of the S2O3 2- ions are consumed, the excess iodine produced in (5) is free to react with starch, turning the solution blue (7). The amount of thiosulfate ions added tells us how much iodine had been produced in the ... WebDec 11, 2024 · Reaction Order and Rate Laws Abstract: The purpose of this lab was to offer students an interactive means of understanding reaction order and rate laws by examining the effects of reactant concentrations in a chemical reaction, analyzing data to determine the order of a reaction, and using observed reactions to summarize rate laws. …
