WebAn additional and helpful consequence of the iodine–thiosulfate reaction is that the concentration of iodide ion in the solution remains constant at its original value. Even though the peroxide–iodide reaction tends to consume iodide ions, the thiosulfate ion immediately returns the iodine to the iodide ion form: -2 22 23--HO 2 SO Web26 feb. 2024 · In non polar solvents, $\ce{KI}$ is soluble but $\ce{KCl}$ is not. This drives the reaction forward to completeness. The difference in solubility in $\ce{NaI}$ and $\ce{NaBr}$ (or the potassium derivatives) is not very appreciable, so the reaction will take place in the forward direction, but will not give a very good percentage yield of product.

Web1 sep. 2024 · In this case we can easily deduce the equation to be: \ce S n + 2 I 2 − > S n I 4. What the given masses tell us is that there is excess tin being added.
