Weigh out the necessary mass of KNO3 to make 50 mL of 1.0 M supporting electrolyte solution. Transfer the KNO3 to a 50- mL volumetric flask and dilute to the mark with deionized Analyte motion water. Ensure the solid is dissolved completely before using the solution. Transfer to a small beaker. This is your supporting electrolyte solution. Weigh out the necessary mass of K3Fe(CN)6 to...
