1) When the Ag+ concentration is1.08 M, the observed cell potential at 298K for anelectrochemical cell with the following reaction is1.654V. What is theZn2+ concentration?
2Ag+(aq)+ Zn(s) >2Ag(s) +Zn2+(aq)
Answer: ___ M
2) A concentration cell similar to the one shown is composed oftwo Cr electrodes and solutions of differentCr3+concentrations. The leftcompartment contains 1.32 MCr3+, and the right compartmentcontains 0.250 MCr3+.
Calculate the cell potential for this reaction at 298 K.
____ volts
In this chromium concentration cell, thecompartment on the left is the __anode or cathode__, and thecompartment on the right is the _anode or cathode__.
