2733-2738p. Abstract: The use of a multicompartment electrochemical cell for the potentiometric determination of solubility product constants of aqueous I–, Br–, SCN–, and Cl– 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 × 10–17, 4.34 × 10–13, 9.01 × 10–13, and 1.44 × 10–10) and the literature values (8.52 × 10–17, 5.35 × 10–13, 1.03 × 10–12, and 1.77 × 10–10, respectively) underscored the feasibility of using the cell for the determination of solubility product constants. ***______{For Hard Copy, Please visit Library.}________*** Anions| Electrochemical cells| Equilibrium constant| Salts| Silver| Analytical Chemistry| Physical Chemistry| Electrochemistry| Potentiometry 0021-9584 https://doi.org/10.1021/acs.jchemed.2c01251 https://doi.org/10.1021/acs.jchemed.2c01251 231120 20231120152659.0
