Chlorine is more reactive than the iodine in potassium iodide solution: When a Group 7 element reacts, it gains one electron to form a negative ion with a stable electronic configuration – a ...

which is a 3% solution of iodine in 90% ethanol, plus some potassium iodide. Another source of iodine is Lugol’s solution ...

The reaction of hydrogen peroxide with potassium iodide is demonstrated in a tall cylinder. Saturated potassium iodide is added to a mixture of soap, glycerin, water, and hydrogen peroxide. Oxygen and ...

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 ...
