Final answer:
Ksp values from Solubility Product Tables are used in Chemistry to calculate the solubility of ionic compounds. The ICE table method is used along with Ksp expression to find ion concentrations in a saturated solution, illustrated by an example with MgCO3.
Step-by-step explanation:
The student's question relates to the use of solubility product constants (Ksp values) in Chemistry. These constants are used to calculate the solubility of slightly soluble ionic compounds. The values of Ksp, which are given for a specific temperature (usually 25°C), can be found in Solubility Product Tables that list Ksp values for various ionic compounds.
To calculate the solubility from Ksp, one must set up an ICE table (Initial, Change, Equilibrium) and determine the concentrations of ions in a saturated solution. For example, the Ksp expression for AgCl would be Ksp = [Ag+][Cl-], and the respective concentrations can be calculated using this expression assuming the concentration of a pure solid is constant.
Let's consider an example calculation with MgCO3. Given Ksp = 2.0 × 10-8 at 25°C, the ion concentrations of [Mg2+] and [CO32-] in a saturated solution can be calculated by establishing equilibrium concentrations from the ICE chart.
