| Video Discription | Chad provides a thorough lesson about galvanic cells (aka voltaic cells). The lesson begins with a comparison and contrast of galvanic cells vs electrolytic cells. Galvanic cells involve a spontaneous reaction that produces energy (electricity), while electrolytic cells involve a nonspontaneous reaction that consumes energy. In the galvanic cell electrons travel through the wire from anode (which is negative) to cathode (which is positive). In the electrolytic cell electrons still travel from anode to cathode but the signs are the opposite (anode is positive and cathode negative). In the galvanic cell the two half reactions take place in separate half-cells the solutions of which are connected by a salt bridge. Anions travel through the salt bridge to the anode, and cations travel through the salt bridge to the cathode in order to maintain electrical neutrality in the solutions of both half-cells. Finally, it is common for the anode to lose mass and the cathode to gain mass in galvanic cells over time, though a common exception is when inert electrodes are used. I've embedded this playlist as a course on my website with all the lessons organized by chapter in a collapsible menu and much of the content from the study guide included on the page.
