As potassium dichromate reacts with iodine potassium iodide to make precipitation of sodium thiosulfate titration of iodine

Because the reaction of potassium dichromate and potassium iodide to generate elemental iodine, which will keep precipitation of sodium thio-sulfate titration of iodine elementary

Because the potassium bichromate meets and the potassium iodide response production idodine simple substance, thus can let the idodine simple substance which the sodium hyposulfite titrate separates out

Since re-potassium and potassium iodide response will be generated and thus to iodine-sulfur-generation sodium sulfate titrimetry subatomic particles will let the iodine single quality

Because the reaction of potassium dichromate and potassium iodide to generate elemental iodine, which will keep precipitation of sodium thio-sulfate titration of iodine elementary
