The Cl− concentration of a solution was determined by coulometric titration. Ag+ generated at the anode reacts with the Cl− in solution, forming the precipitate AgCl(s). The end point is determined when an increase in current is detected due to excess Ag+ in solution. A current of 0.500 A was applied for 17.55 min through a 25.00-mL solution containing an unknown Cl− concentration. Calculate the Cl− concentration. (Report to 4 decimal places)
