I. The reaction between iodide and hydrogen peroxide produces triiodide. The triiodide ions are reduced back to iodide by thiosulfate at a much faster rate, until the thiosulfate is consumed. Then the ...

I. The reaction between iodate and bisulfite in acid medium produces iodine. Solutions A (iodate) and B (bisulfite) are mixed at room temperature in differing concentrations, producing a blue-black ...

The first reaction in the video below demonstrates how iodine and starch can be used as a reagent to detect peroxide. A tiny drop of glucose solution turns the iodine-starch suspension a deep blue ...

It involves a series of redox reactions where iodine is produced and immediately reacts with starch, forming a starch-iodine complex that creates the visible colour changes. The timing of the ...

This glucose is: After a few minutes, the parts of the leaf that contain starch turn the iodine from brown to blue/black. Variegated leaves have green parts (where the cells contain chlorophyll ...

start timing immediately remove a sample immediately, and test it with iodine solution sample ... taken for the disappearance of starch is not the rate of reaction. We can calculate the rate ...
