Clarifying from textbook

Postby claudia_1h » Sat Feb 22, 2020 6:26 pm

In the textbook, it says "In a galvanic cell, a spontaneous chemical reaction draws electrons into the cell through the cathode, the site of the reduction, and releases them at the anode, the site of the oxidation."

Can someone explain the drawing of electrons through the cathode? Because I thought in a galvanic cell, electrons flow anode to cathode... I'm trying to understand how galvanic cells function conceptually, so if someone has a good way of explaining it, please do!

In Galvanic cells the electrodes flow from cathode to anode.

Actually, that’s incorrect - in galvanic cells the electrodes flow from anode to cathode, or from the site of the oxidation reaction to the site of the reduction reaction, in other terms. However, to keep the electrodes neutrally charged, anions flow toward the anode and cations flow toward the cathode. This may be what you were confused about in the diagram in the textbook.
