Appearance:Potassium persulfate appears as a white crystalline solid. Specific gravity 2.477. Decomposes below 100°C.
Density:2.477 g/cm3
Melting Point:100ºC
Boiling Point:1689ºC
Flash Point:NotºCombustible
Refractive Index:INDICES OF REFRACTION: 1.461, 1.467, 1.566
Water Solubility:Solubility in water, g/100ml at 20°C: 5.2
Storage Conditions:Keep containers closed and store in cool dark places.
Vapor Density:9.3 (vs air)
Toxicity:LD50 orally in Rabbit: 802 mg/kg
Odor:ODORLESS
PH:AQUEOUS SOLN IS ACIDIC
Experimental Properties:Decomposes below 100 °C
Air and Water Reactions:Water soluble. Slowly decomposed by water. The salt rapidly liberates oxygen when heated, and especially so when wet.
Reactive Group:Oxidizing Agents, Strong
Reactivity Alerts:Strong Oxidizing Agent
Reactivity Profile:POTASSIUM PERSULFATE is an oxidizing agent. Noncombustible but accelerates the burning of combustible material. Potassium persulfate plus a little potassium hydroxide and water released sufficient heat and oxygen to ignite a polythene (polyethylene) liner in a container. [MCA Case History 1155. 1955].
