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 …
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 …
Does the cathode always attain a positive charge or is it just a ...
Jul 12, 2024 · Being a cathode or anode is not directly related to the charge or potential of the electrode, but to direction of the electron transfer in closed circuits. (or the direction that would …
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.
electrons - Why don't we observe protons deflecting in J.J.
Aug 21, 2024 · The cathode rays (electrons) will be attracted towards the positive plate. This will limit the supply of electrons to the region closer to the anode. Due to the limited supply of high …
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 …
Half cells: difference between E (cell) = E (cathode}-E (anode) & E ...
2 When do I use each of the above? If I use one or the other they give me difference results. For example, I'm trying to put the Volts into an equation to find standard free energy change. …
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.
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? …
physical chemistry - How to correctly define anode and cathode ...
Sep 9, 2020 · In a cathode ray tube experiment, the CRT would be the area of interest and electrons are ejected from the cathode into the tube and are incident on the glass behind the …
