Standard molar enthalpy (heat) of formation at 298.15 deg K is -928.4 kJ/mol (crystal); Standard molar Gibbs energy of formation at 298.15 deg K is -820.8 kJ/mol (crystal); Standard molar entropy at 298.15 deg K is 107.5 J/mol K (crystal); Molar heat capacity at constant pressure at 298.15 deg K is 100.6 J/mol K (crystal)|Pale, bluish-green monoclinic odorless crystals or granules. Efflorescent in dry air; forms tetrahydrate @ 56.6 °C and monohydrate @ 65 °C; density 1.897. Sol in water; practically insol in alc. /Ferrous sulfate heptahydrate/|Odorless; has saline, astringent taste. /Ferrous sulfate heptahydrate/|White, triclinic crystals; index of refraction 1.526, 1.536, 1.542; density 2.2; MP 300 °C losing 5H2O; sol in cold & hot water, insol in alc. /Ferrous sulfate pentahydrate/|Green monoclinic prisms; index of refraction 1.533, 1.535; density 2.23-2.29. /Ferrous sulfate tetrahydrate/|pH 3.7 (10%) solution; hygroscopic /Ferrous sulfate heptahydrate/|Each part of ferrous sulfate heptahydrate requires 0.03 parts of oxygen or 0.126 parts of chlorine for oxidation to the ferric state. /Ferrous sulfate heptahydrate/|In moist air, oxidizes to yellow-brown basic iron(III) sulfate. Aqueous solutions tend to oxidize with the rate increasing with increasing pH, temperature, and light /Ferrous sulfate heptahydrate/|Sugar, glycerin, & many organic hydroxy acids hinder precipitation. In neutral solution, soluble carbonates, phosphates, & oxalates produce precipitation. /Ferrous salts/
Water soluble
Reducing Agents, Strong
Weak inorganic reducing agents, such as FERROUS SULFATE, react with oxidizing agents to generate heat and products that may be flammable, combustible, or otherwise reactive.
Not flammable (USCG, 1999)
