The anode is regarded as negative in a galvanic (voltaic) cell and the cathode is deemed positive. This seems appropriate because the anode is the origin of electrons and where the electrons flow is the cathode.
Aug 9, 2023 · In a galvanic cell, the anode undergoes oxidation and functions as the negative electrode, while in electrolysis, it becomes the positive electrode. Conversely, the cathode facilitates reduction and serves as the positive electrode in a galvanic cell but acts as the negative terminal in electrolysis. DIY.
The cathode can be negative like when the cell is electrolytic (where electrical energy provided to the cell is being used for decomposing chemical compounds); or positive as when the cell is galvanic (where chemical reactions are used for generating electrical energy).
Answer: The anode is negative in a galvanic cell and the cathode is positive. It is because of the fact that anode is the origin of electrons and where the electrons flow is the cathode. Share with friends
Oct 10, 2023 · When naming the electrodes, it is better to refer to the positive electrode and the negative electrode. The positive electrode is the electrode with a higher potential than the negative electrode. During discharge, the positive electrode is a cathode, and the negative electrode is an anode.
Nov 21, 2019 · The cathode is the negatively charged electrode. The cathode attracts cations or positive charge. The cathode is the source of electrons or an electron donor. It may accept positive charge.
May 7, 2019 · In a vacuum tube or cathode ray tube, the cathode is the negative terminal. This is where electrons enter the device and continue into the tube. A positive current flows out from the device.
