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 added an extra …
electrolysis - Is a pure copper cathode necessary in the electrolytic ...
Nov 27, 2024 · The cathode (a thin copper sheet) is simply left in the final product of the refinery (a thick copper plate) - no one needs them separated, they are the same substance. The new cathode …
Half cells: difference between E (cell) = E (cathode}-E (anode) & E ...
The cathode is actually the reduction step, and the anode is the oxidation step. A useful mnemonic I learned from my chemistry professor is a red cat and an ox. Interestingly, cathodes in …
Why is mass gained at the cathode? - Chemistry Stack Exchange
Apr 2, 2017 · 0 So with the cathode, there were no Cu2+ C u 2 + ions that initially dissolved in the solution. Rather, they were there from the beginning and once the copper metal cathode was added …
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.
electrochemistry - Do ions still "conduct electricity" if a physical ...
Dec 19, 2020 · Suppose the cathode and the anode are placed into different solutions in different containers, anode still attracts anions and cathode still attracts cations. So that there should still be …
