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
