用CaCl2溶液滴入分别盛有NaHCO3溶液和Na2CO3溶液的试管中,不能简单地认为有白色沉淀生成的溶液就是Na2CO3溶液,无沉淀生成的原溶液就是NaHCO3溶液。
The CaCl2 solution was dropped into the test tubes containing the NaHCO3 solution and the Na2CO3 solution, respectively, and it could not simply be said that the solution formed by the white precipitate was the Na2CO3 solution, and the original solution without the precipitate was the NaHCO3 solution.
