补充资料:硫酸铬
分子式:Cr2(SO4)3 
CAS号:

性质:紫色或红色粉末。相对密度3.012。不溶于水、酸,微溶于乙醇。但当有少量二价铬盐时就可溶于水或酸。一般有两种水合物。18水合物:Cr2(SO4)3·18H2O,黑紫色立方或八面体晶体。相对密度1.7(22℃),100℃时脱去12分子水。易溶于水,溶于乙醇。15水合物:Cr2(SO4)3·15H2O,紫色无定形固体。相对密度1.867(17℃)。熔点100℃。大于100℃时脱去10分子水,溶于水,不溶于乙醇。水合硫酸铬溶液与硫酸钾溶液混合后可制得铬矾。由硫酸与氢氧化铬作用先制得含水硫酸铬,再于325℃和1333.2Pa压力下经脱水而得无水物。用于印染、陶瓷、不溶性凝胶以及制造含铬催化剂、鞣革、油漆和油墨。
