Determining the signs of the electrodes in a Electrolytic Cell

Postby Virpal Gill 1B » Mon Feb 19, 2018 8:48 pm

I was having trouble understanding why the sign of the anode in an electrolytic cell is positive even though electrons are leaving the cell because reduction is taking place there. Does anyone else understand this concept?

In the anode, oxidation is occurring. In oxidation electrons are leaving the cell, making the charge on the cell less negative and more positive. For the cathode, reduction is taking place meaning that the cell is gaining electrons and gaining negative charge.
