Which is anode and which is cathode? - Chemistry Stack Exchange
Feb 15, 2017 · The cathode is the electrode, where substances are gaining electrons and are reduced. The tricky part for the memorising is, anodes and cathodes flip the position, when the current is …
Positive or Negative Anode/Cathode in Electrolytic/Galvanic Cell
Sep 27, 2014 · 65 In a galvanic (voltaic) cell, the anode is considered negative and the cathode is considered positive. This seems reasonable as the anode is the source of electrons and cathode is …
Why is the anode in a galvanic cell negative, rather than positive ...
Feb 18, 2022 · Similarly in diagrams comparing galvanic and electrolytic cells, electrons move away from the anode to the cathode in the electrolytic cell, making the anode positive. This makes perfect …
Direction of flow of current in electrolytic cell [duplicate]
Sep 13, 2017 · In an electrolytic cell, does current flow from Anode to Cathode or Cathode to Anode I've seen various websites, including this and this, but they seem to contradict each other.
What is the flow of electrons, cations, and anions in a voltaic cell ...
Apr 10, 2019 · According to my notes and many sources on the internet, electrons and cations both travel from the anode (A in the image) to the cathode (B in the image). The idea of the salt bridge is …
Cathode + Anode + Rechargeable battery - Chemistry Stack Exchange
May 15, 2014 · The cathode is a metal oxide and the anode consists of porous carbon. During discharge, the ions flow from the anode to the cathode through the electrolyte and separator; charge …
Why do positive ions go to the cathode? - Chemistry Stack Exchange
Jul 4, 2017 · 8 In electrolysis why do positive ions go to the cathode? Since the cathode is positive, won't the positive ions face repulsion at the cathode and would require more energy? I understand …
