| 单词 | solubility product |
| 释义 | solubility product Symbol Ks. The product of the concentrations of ions in a saturated solution. For instance, if a compound AxBy is in equilibrium with its solution AxBy(s) ⇌ xA+(aq) + yB-(aq) the equilibrium constant is Kc = [A+]x[B-]y/[AxBy] Since the concentration of the undissolved solid can be put equal to 1, the solubility product is given by Ks = [A+]x[B-]y The expression is only true for sparingly soluble salts. If the product of ionic concentrations in a solution exceeds the solubility product, then precipitation occurs |
