Question

Electrolysis is carried out on a solution of silver nitrate for2.00 h. The platinum cathode, which has a mass of 25.0782 g, weighs25.2794 g after the electrolysis. The platinum anode weighs thesame before and after the electrolysis.

a) draw diagram of electrolytic cell. include charges andhalf-reactions occuring at each electrode, and show the directionelectrons are flowing.

b) What must have been the magnitude of the current used in thiselectrolysis?

c) What minimum voltage must have been used in thiselectrolysis? Assume standard conditions.

d) What volume of gas forms at the anode if it is measured at 25degrees celsius and 755mmHg?

Please show work. Answers are: (b) 0.0250 A (c) 0.43 V (d) 11.5ml of O2
