bismuthous

1.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.

用化学热力学基础理论和方法研究了硫化铋在无氧化性强酸和可溶性碱金属卤化物溶的溶解性。

2.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.

结果表明硫化铋只能溶于氢卤酸（除氢氟酸外）、稀硫酸与碱金属卤化物的混合，能溶于稀硫酸。
