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 …
Why is mass gained at the cathode? - Chemistry Stack Exchange
Apr 2, 2017 · 0 So with the cathode, there were no $\mathrm {Cu}^ {2+}$ ions that initially dissolved in the solution. Rather, they were there from the beginning and once the copper …

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 …
Why do they use graphite electrodes in the Hall–Héroult process?
During the electrolysis process, aluminium is deposited at the cathode and oxygen is liberated at the anode. Some of this oxygen reacts with the carbon in the graphite to form carbon-dioxide, …
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.
