Section 10 - STABILITY AND REACTIVITY
Chemical Stability:
Stable at room temperature in closed containers under normal storage and handling conditions. FeSO4.7H2O oxidizes in moist air forming a brown coating of basic ferric sulfate. Aqueous solutions are oxidized slowly by air when cold, rapidly when hot; rate of oxidation increased by addition of base or exposure to light.
Conditions to Avoid:
Light, dust generation, moisture, excess heat, prolonged exposure to air.
Incompatibilities with Other Materials:
Strong oxidizing agents, bases, lead acetate, silver salts, lime water, carbonates, potassium tartrate, gold salts, potassium iodide, sodium borate, sodium tartrate, tannin.
Hazardous Decomposition Products:
Oxides of sulfur, oxides of iron.
Hazardous Polymerization: Has not been reported.
