What is Solubility Product?
Solubility Product, denoted as Ksp, is the equilibrium constant that defines how sparingly soluble compounds behave when immersed in water. Solubility Product can be defined as the maximum product of a molar concentration of ions, raised to their powers produced due to dissociation of compound.
In other words, Solubility Product is an indication of solubility. Low value of solubility product indicates low or decreased solubility while high value of solubility product indicates high solubility. At a given temperature, Solubility Product is Constant.
Principle of Solubility Product
The principle of solubility product is rooted in the concept of equilibrium. For a sparingly soluble salt like silver chloride (AgCl), when it dissolves in water, it forms silver ions (Ag+) and chloride ions (Cl–). The equilibrium expression for this process is represented as:
AgCl (s) ⇌ Ag + (aq) + Cl– (aq)
This leads to the Ksp expression: Ksp= [Ag+] × [Cl–]. This represents the equilibrium concentration of Silver and chloride ions in solution at a constant temperature. At 25 degree Celsius, its Solubility Product Constant is approximately 1.77 × 10−10. This indicates at equilibrium, Solubility of silver chloride is low in water,
Solubility Product – Definition, Formula, Significance
Solubility Product Constant, denoted as Ksp is an equilibrium constant which quantifies how much of a solute substance can dissolve in water. Solubility Product (Ksp) aims to explain the maximum amount of substances (solutes) that can dissolve in water (solvents) at a given temperature. it depends on the temperature, its value increases with the increase in temperature, which increases solubility. This article aims to learn Ksp, exploring its principles, formulas, constants, and practical applications.
