Abstract
- The solubility of sulfides is discussed in this article based on the factors that can influence this property, such as predominant type of chemical bonds and structures formed in many compounds. For soluble sulfides, considerations are made on the thermodynamic parameters and the acid-base equilibrium, since the sulfide anion is extensively hydrolyzed in aqueous solutions. On the other hand, for the insoluble sulfides, the discussion concerned the influence of structural factors that will be determinant for the low solubility.
