53. Solution to Chemistry Problem

10. The coulometric titration of 10.0 ml of sodium thiosulfate solution with iodine generated in a coulometric cell from potassium iodide required 22 min at a current of 300 mA. Calculate the amount of electricity consumed and the concentration of the sodium thiosulfate solution. Write the equations of electrochemical reactions and propose a method for recording the end point of the titration.
