In a 3-electrode cell filled with a solution of dopamine, the potential of the working electrode is scanned from +0.2 V to +0.7 V vs. a Ag/AgCl reference electrode. The current rises exponentially and then peaks at +0.48 V followed by a decay (gradual decrease) in current. What causes the decrease in current? The concentration of dopamine near the electrode decreases. All of the dopamine in the solution is consumed. A second reaction begins to interfere at such positive potentials....

A 100.00mL solution of 0.100 M NaCl was titrated with 0.100 M AgNO3. A SCE indicator electrode (E+=0.241V) was the anode and an Ag wire was the cathode for this precipitation titration. Calculate the voltage after the addition of 65 mL of AgNO3 given that Ksp(AgCl)=1.8x10^(-10). Answer=0.081 V. Please show steps, thank you! :)
