请教高手:硫酸亚铁在高温多少度下会分解?分解会生产什么产物?谢谢?具体的温度是多少?... On heating, iron(II) sulfate first loses its water of crystallization and the original green crystals are converted into a brown colored anhydrous solid. When further heated, the anhydrous material releases sulfur dioxide and white fumes of sulfur trioxide, leaving a reddish-brown iron(III) oxide. Decomposition of iron(II) sulfate begins at about 680 °C (1,256 °F).2 FeSO4 → Fe2O3 + SO2 + SO3,查看更多
