10. STABILITY & REACTIVITY: Stability: Stable at room temp in closed containers under normal storage & 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. Avoid: Light, dust generation, moisture, excess heat, prolonged exposure to air. Incompatibilities: Strong oxidizing agents. Haz Decomp: see section 5
