bismuthous

1.Which indubitably indicate that the bismuthous sulfide can only dissolve in halogen acid except hydrofluoric acid, the mixed solution of dilute sulfuric acid and alkali halide.

结果表明硫化只能于氢卤酸（除氢氟酸外）、硫酸与碱金属卤化物混合液，不能于硫酸。

2.It is studied further that the dissolubility of the bismuthous sulfide in the solutions of the non-oxidative strong acid through the experiment by means of chemical thermodynamics.

运用化学热力学基础理论和方法研究了硫化在无氧化性强酸和可性碱金属卤化物液解性。
