Students in CH145 set a campus record for the longest human salt bridge by connecting the anode and cathode of a Zn/Cu electrochemical cell with a 28-student chain.  The cell produced a potential of 1.3 volts confirming that we had no weak electrolytes in this group of students.   Our next effort will try to break the Virginia Tech record of a 180-student salt bridge.
