沉淀溶解度的几个问题讨论

On the Problems of Solubility on Deposition

本文讨论了沉淀稀释时及两性氢氧化物和硫化物沉淀在不同PH值条件下的溶解度变化。沉淀的溶解度计算是化学中一个很重要的问题,某些教材虽有一些讨论,但限于篇幅未作深入的介绍。本人从多年教学经验体会中对以下三个问题试图在理论上予以阐述,供教学同仁参考。

In the article, while depositing and deluting the change of solubility about amphiprotic hydroxide and sulfide deposition will be discussed unde the different PH conditions. The article is also a complement on deposition and dessolution in basic Chemistry.
