摘要
通过实验讨论三硫化二砷在无氧化性强酸、强碱溶液中的溶解性。提出三硫化二砷由于存在水解平衡导致难溶于无氧化性强酸而易溶于强碱溶液中。
The paper discusses the solubility of the arsenious sulfide in the nonoxidizahle strong acids.alkaline solution by way of the experiment. It is put forth that the arsenious Sulfide can’t dissolve in the nonoxidizable strong acids. but can dissolve easily in the alkaline solution because of existence of hydrolytic equilibrium.
