What is the Ksp value for silver chloride (AgCl)?

The solubility product constant (Ksp) for silver chloride (AgCl) represents the equilibrium between the solid form of the salt and its constituent ions in a saturated solution. When AgCl dissolves, it dissociates into silver ions (Ag⁺) and chloride ions (Cl⁻). The Ksp expression for this process can be represented as:

[ Ksp = [Ag^+] [Cl^-] ]

At equilibrium, if the concentration of Ag⁺ in solution is s and the concentration of Cl⁻ is also s (since they dissociate in a 1:1 ratio), then the Ksp can be expressed as:

[ Ksp = s \cdot s = s^2 ]

For silver chloride, the solubility product constant is a measure of how much AgCl can dissolve in water at a specific temperature, typically at room temperature. The value of 1.8 x 10^-10 is the widely accepted Ksp for AgCl, indicating that at equilibrium, the concentrations of the ions are quite low, reflecting the low solubility of silver chloride in water.

This value helps in understanding the extent to which silver chloride can dissolve, which is critical in various applications such
