不仅从化学平衡的角度对稀酸溶解FeS及CuS的原理进行了分析,而且还利用热力学偶合反应原理及溶解自由能数据,阐明了两种金属硫化物在稀酸中溶解性不同的原因。
The principle of dilute acid dissolving FeS and CuS was analyzed not only from the viewpoint of chemical equilibrium, but also the reasons for the different dissolubility of the two kinds of metal sulphides in dilute acid by using thermodynamic coupling reaction theory and data of free energy of dissolution.
