The lead electrode is immersed in a solution containing 0.01 m sodium iodide, saturated with lead iodide; paired with n.c.e, it serves as an anode. Calculate the PR (PbI2) if the system potential is 0.54 V. E0Pb2 / Pb0=-0.126 V. E (n.c.e) = 0.247 V

If you do not open the file - install the RAR archiver. Inside the archive you will find a solution in Word format.
