Which is anode and which is cathode? - Chemistry Stack Exchange
Feb 15, 2017 · The actual question is, if the cathode indeed is the negative electrode? So the question is still: Why would electrons move towards the cathode, which is negative? I have …
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 …
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.
