Brief Overview

Potassium triiodide is a dark brown-violet solution of potassium iodide with iodine in water. A small amount may be used for emergency disinfection of drinking water.

The iodide combines with metallic iodine to form a high concentration of potassium triiodide (KI3) solution. There is some excess potassium.
