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.
结果表明硫铋只能于氢卤酸(除氢氟酸外)、硫酸与碱金属卤的混合液中,不能于硫酸中。
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.
