| Abstract: |
The use of a multicompartment electrochemical cell for the potentiometric determination of solubility product constants of aqueous I[superscript -], Br[superscript -], SCN[superscript -], and Cl[superscript -] salts of silver is presented. An electrochemical cell presented in this study contained multiple half-cells made of disposable drinking straws, a silver wire electrode housed in a plastic syringe, and a reference electrode. An agreement between the solubility product constant values of AgI, AgBr, AgSCN, and AgCl obtained by the students (7.84× 10[superscript -17], 4.34 × 10[superscript -13], 9.01 × 10[superscript -13], and 1.44 × 10[superscript -10]) and the literature values (8.52 × 10[superscript -17],5.35 × 10[superscript -13], 1.03 × 10[superscript -12], and 1.77 × 10[superscript -10], respectively) underscored the feasibility of using the cell for the determination of solubility product constants. |
