Potassium Iodide (KI) powder is a white crystalline compound supplied in a 100-gram container. This highly soluble chemical is available in reagent or technical grades, making it suitable for laboratory and industrial applications. The powder dissolves readily in water and moderately in ethanol. Store in a cool, dry, dark location in a sealed container to maintain stability, as prolonged exposure to moisture and light may cause gradual oxidation and slight discoloration. Confirm purity grade on the product label before use.
