化工生产品中腐蚀性，：烧碱、纯碱、浓稀硫、碳、醋等。

The preparation of zinc sulfate heptahydrate and copper sulfate pentahydrate from calcined zincblende was investigated.

用经高温煅烧后闪锌矿石与稀硫反应制备七水硫锌和五水硫铜。

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（除氢氟外）、稀硫与碱金属卤化液中，不能溶于稀硫中。
