Pure product is dark purple shiny powder. Stable below 198 °C. It is very soluble in water and becomes a light purple-red solution. After standing, it will release oxygen and precipitate hydrated ferric oxide. The alkalinity of the solution increases with decomposition and is quite stable in a strong alkaline solution, making it an excellent oxidant. It has an efficient disinfection effect.
