Relation between solubility product and molar solubility
Answers
A substance’s solubility product (Ksp) is the ratio of concentrations at equilibrium.
The molar solubility of a compound can be calculated directly from its solubility product.
Even if the solubility products of two compounds are similar, their molar solubilities can be very different.
Scientists take advantage of the relative solubilities of compounds to separate or identify them.
Molar Solubility
A substance’s solubility product (Ksp) is the ratio of concentrations at equilibrium. Molar solubility, which is directly related to the solubility product, is the number of moles of the solute that can be dissolved per liter of solution before the solution becomes saturated. Once a solution is saturated, any additional solute precipitates out of the solution. The units are molarity (M), or mole liter-1 (mol/L).
Relative Solubility
If compounds have different solubilities, or relative solubilities, they can be separated. For example, in the process of extraction, scientists take something dissolved in one liquid and force it to become dissolved in another liquid. Caffeine must be extracted from coffee beans in order to be used in beverages such as soda. Typically, the caffeine is dissolved in carbon dioxide that has been heated to over 300 K and pressurized to 73 atm, making it a liquid. Then, the temperature is lowered (lowering the solubility of the caffeine in carbon dioxide), and water is added. The system is allowed to reach equilibrium. Since caffeine is more soluble in water than it is in carbon dioxide, the majority of it goes into the water.
A technique called paper chromatography also takes advantage of the relative solubilities of compounds
if any mistakes please forgive me plz
