硫酸铁 铁的硫酸盐的统称。 硫酸亚铁FeSO4为无色粉末；相对密度3.4；加热分解；与水作用,生成七水合物FeSO4·7H2O,俗称绿矾。绿矾为蓝绿色晶体；熔点64℃，密度1.898克／厘米3；加热到90℃时,失去6分子结晶水；小心加热到300℃时,失去全部结晶水。绿矾在空气中缓慢风化，表面层被氧化呈黄褐色；溶于水、甘油、无水甲醇，微溶于乙醇；有还原性，能与碱金属的硫酸盐（包括硫酸铵）形成稳定、不易氧化的硫酸复盐M姟Fe(SO4)2·6H2O(MⅠ为+1价金属)。 硫酸亚铁是工业上用硫酸处理含铁矿物的副产品，也可由铁与稀硫酸作用而得；可做还原剂、净水剂、煤气净化剂、媒染剂、杀虫剂、肥料、补血剂，也用来制墨水和颜料。 硫酸铁Fe2(SO4)3为黄色粉末,极易潮解而成棕色液体；密度 3.097克／厘米3(18℃)，加热到480℃时分解。它的水合物很多，常见的是九水合物Fe2(SO4)3·9H2O，为棕黄色晶体,密度2.1克／厘米3;175℃时失去7分子水。硫酸铁溶于水、无水乙醇；不溶于浓硫酸。其水溶液因三价铁离子的水解呈棕红色，容易与碱金属硫酸盐（包括硫酸铵）形成硫酸复盐MIFe(SO4)2·12H2O。硫酸铁可用硝酸、过氧化氢等氧化剂氧化含硫酸的硫酸亚铁热溶液而制得，也可用氢氧化铁与硫酸作用而得；可做净水剂、媒染剂、颜料和药物。
