氢氧化镥是一种无机化合物化学式为Lu(OH)3

制备

[编辑]

氯化镥和碱反应,生成碱式盐Lu(OH)2Cl的沉淀,反应液中放置后转化为Lu(OH)2.5Cl0.5,最后陈化为Lu(OH)3[2]

LuCl3+2 NaOH→Lu(OH)2Cl+2 NaCl
Lu(OH)2Cl+0.5 NaOH→Lu(OH)2.5Cl0.5+0.5 NaCl
Lu(OH)2.5Cl0.5+0.5 NaOH→Lu(OH)3+0.5 NaCl

化学性质

[编辑]

氢氧化镥可溶于,生成镥盐:

Lu(OH)3 + 3 H+ → Lu3+ + 3 H2O

氢氧化镥受热分解,先生成LuO(OH),继续加热得到Lu2O3[1]
