1. This amount is given by the solubility product , K sp. 2. It's usually called the solubility product constant. 3. Other constants for dynamic equilibrium involving phase changes, include partition coefficient and solubility product . 4. Solubility will show a clear increase in presence of diverse ions as the solubility product will increase. 5. If the solubility product of the impurity is exceeded, some of the impurity will co-precipitate. 6. In an ideal situation the solubility product of the impurity, B, is not exceeded at any temperature. 7. Note : pK sp = 15.097 where p is the-log and K sp is the solubility product . 8. This results in an apparent solubility product for CaCO 3 that is 193 times higher in 350 seawater than in distilled water. 9. Where F s is the scale saturation ratio, defined as the ratio of the activity product to the solubility product of the salt. 10. As a consequence, the product of the concentrations is far in excess of the solubility product , so copper ( I ) iodide precipitates.
