对三价铁和二价硫反应的商讨

Discusion About Reactions of Ferric Iron And Divalent Sulfide

本文通过实验论证了三价铁和二价硫无论在酸性或碱性条件下只发生氧化还原反应,不发生成三硫化二铁的沉定反应。沉淀中含有的少量三价铁是由于共沉淀所致。

The article provides proof that when ferric iron and divalent sulfide are in acidity or bacicity, it results in oxidation-reduction, reaction but not in precipitating reaction of ironic trisulfide, and the snail amount of ferric iron in the sediment is the result of the cosediment.
