The balanced chemical equation for the reaction between thiosulfate ... WebThiosulfate was oxidized to tetrathionate while the iodine was reduced to iodide ions according to the reaction: 2 S 2 O 3 2-+ I 2 → S 4 O 6 2-+ 2I. Iodine did not accumulate in …
WebObjective The purpose of this experiment is to use the reduction-oxidation reaction between known 2amount of thiosulfate ion (S 2 O 3 -) and iodine (I 2 ) as a measuring tool to determine the rate of reaction between persulfate (S 2 O 8 2-) and iodide (I-) ions; to determine the rate law of reaction by initial rate method. WebThiosulfate ions can react with iodine molecules (I 2 ), one of the products of the previous reaction, as shown in equation 22-2. The reaction between S 2 O 3 2-and I 2 is extremely fast; hence, the I 2 produced in reaction 22-2 is immediately consumed. When S 2 O 3 2-is present in the solution, I 2 cannot exist concurrently. But once S 2 O
