n what circumstance would a voltmeter read a negative voltage when connected to an anode and a cathode in an electrochemical cell? The black (-) lead is connected to an electrode where an oxidation is occuring, and the red (+) lead is connected to an electrode where a reduction is occuring. The black (-) lead is connected to an electrode where an reduction is occuring, and the red (+) lead is connected to an electrode where a oxidation is occuring. Both leads are connected to electrodes where oxidation reactions are occuring. Both leads are connected to electrodes where reduction reactions are occuring. A negative potential reading is impossible.
