Nesquehonite (MgCO2·3H2O) or Mg(HCO3,OH)·2H2O (NSQ), hydromagnesite [Mg5(CO3)4(OH)2·4H2O] (HMG), and dypingite [Mg5(CO3)4(OH)2·XH2O] where X = 5, 6 (DYP) are the most common phase among them. NSQ is crystallized from an aqueous solution including Mg2+ ions and ...
碱式碳酸镁[Mg5(OH)2(CO3)4·4H2O]是重要的化工产品。一种以白云石[主要成分为CaMg(CO3)2,含少量SiO2、Fe2O3等]为原料制备碱式碳酸镁的实验流程如下 已知:碱式碳酸镁在高温水溶液中会部分分解为氢氧化镁。 (1)“煅烧”时生成的两种金属氧化物的化学式为 。 (2)“消化”时,氧化镁在沸水中转化为...
有这种物质,楼主先看化合价嘛,化合价之和为零 他是一种复盐,可以改写的。可以改写为Mg(OH)2@4MgCO3,@表示圆点,手机打不出来。碱式碳酸镁化学式是,Mg2(OH)2CO3 也可以写成Mg(OH)2-MgCO3 中间打点啊!所以他和碱式碳酸镁不是同种物质 ...
