Potassium Iodide Starch Paper, 100pk is a qualitative test paper impregnated with potassium iodide and starch for detecting oxidizing agents in liquid samples and solutions. When oxidizing agents such as free iodine, chlorine, or peroxides are present, the paper undergoes a color change (typically blue to purple) as a result of the oxidation of potassium iodide to iodine, which reacts with starch to form a visible color response. This makes the strips suitable for quick indication of oxidizer presence in field testing, environmental sampling, and hazard screening.
Potassium iodide starch paper is widely used to preliminarily screen for oxidizing substances in solutions, including nitrite and free chlorine, by visually detecting presence based on color change reactions.
