For the general dissociation of a sparingly soluble salt: In this equation, x+ and z– are the magnitude of the positive and negative charge, respectively; the equilibrium constant expression (solubility product expression) is. The metal, having lost one or more electrons, forms a cation, an ion with a positive charge; the nonmetal, having gained one or more electrons, becomes an anion, an ion with a negative charge. Knowing this pattern is useful in many aspects of chemistry, including predicting the bonding situation of a particular atom and in the prediction of the geometry of a covalent compound. 0000038193 00000 n
