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 …
Positive or Negative Anode/Cathode in Electrolytic/Galvanic Cell
Jan 22, 2017 · 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 …
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 anode. The …
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. $$\Delta …
electrons - How did J. J. Thomson prove that the cathode rays were …
Dec 11, 2018 · Cathode "rays" had been known for some time before Thomson. They were first observed as experiments in gas discharge tubes started to exploit better and better vacuums (the …
How are cathode rays produced? - Chemistry Stack Exchange
Oct 28, 2014 · Why cathode rays are produced if pressure of the gas discharge tube is lowered to about $10^{-4}$ atm? How bombardment of glass of gas discharge tube from cathode ray result in a faint …
Positive and negative terminal in an electrolytic cell
Oct 2, 2023 · At electrolysis, the cathode (absorbing electrons) is usually more negative electrode. But if for some reasons you reverse the voltage and current direction, the cathode is more positive electrode.
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 …
Why is the electrode potential for a cathode positive?
Jul 23, 2020 · The cathode always accepts electrons (reduction). The postive electrode is the one with the higher potential than the negative electrode. Since the potentials are all defined relative to a …
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 …
