Consider the following galvanic cell: Calculate the $K_{\text {sp }}$ value for $\mathrm{Ag}_{2} \mathrm{SO}_{4}(s)$. Note that to obtain silver ions in the right compartment (the cathode compartment), excess solid $\mathrm{Ag}_{2} \mathrm{SO}_{4}$ was added and some of the salt dissolved.

Key Concepts

Galvanic Cells

Galvanic cells are electrochemical cells that convert chemical energy into electrical energy through spontaneous redox reactions. They consist of two half-cells connected by a salt bridge or porous barrier, where each half-cell contains an electrode and an electrolyte. The potential difference generated between the electrodes arises from differences in their tendencies to lose or gain electrons, and this voltage can be related to the chemical reaction’s equilibrium constant.

Nernst Equation

The Nernst equation is a fundamental relation in electrochemistry that connects the cell potential to the concentrations (or activities) of the chemical species involved. It is used to calculate how the voltage of an electrochemical cell changes as the reaction proceeds or when different concentrations are present, allowing for the determination of equilibrium constants such as the solubility product in cases where ion concentrations are controlled by a sparingly soluble salt.

Solubility Product Constant (Ksp)

The solubility product constant, Ksp, is an equilibrium constant used to describe the dissolution of a sparingly soluble salt. It is defined by the product of the molar concentrations of the ions raised to the power of their stoichiometric coefficients at equilibrium. Understanding Ksp is essential in predicting whether a precipitate will form in a solution and in quantifying the solubility of the salt under specific conditions, which can be linked to cell potential measurements in an electrochemical cell.
