Saturated potassium iodide is added to a mixture of soap, glycerin, water, and hydrogen peroxide. Oxygen and water vapor are trapped in soap bubbles resulting in a long, soapy snake. 1. Prepare soap ...

The reaction between iodide and hydrogen peroxide produces triiodide ... Then the triiodide ions form a blue starch-pentaiodide complex, causing the solution to turn from clear to dark. The initial ...

“Through π-π stacking and hydrogen bonding interactions between FBA and the lead iodide (Pb-I) framework, we significantly stabilized the PbI6 skeleton, addressing iodine loss—a key factor ...
