有关盐类水解的一系列化学反应涉及到的基础知识比较广泛,互相牵制的因素比较复杂。有的问题要用水解的原理解释,如硫酸铝溶液和碳酸钠溶液混和生成二氧化碳气体和氢氧化铝白色沉淀,化学方程式是 The basic knowledge involved in the series of chemical reactions involving salt hydrolysis is quite extensive, and the factors that prevent each other are more complex. Some problems need to be explained by the principle of hydrolysis. For example, aluminum sulfate solution and sodium carbonate solution are mixed to generate carbon dioxide gas and white precipitation of aluminum hydroxide. The chemical equation is
