Although voltaic and electrolytic cells have some differences, some things that they have in common are the processes that happen at the anode and cathode. What redox process takes place at the anode and what redox process takes place at the cathode?

oxidation takes place at the anode while reduction takes place at the cathode.

Explanation:

In the process of electrolysis the electric current is passed accross an ionic compound, the compound could either be in it's molten state or dissolved in a solvent. When there is connection between the anode and cathode are by a wire, there is always a flow of electrons from anode to cathode.

A redox reaction reffers to a chemical reaction in which there are both process of oxidation and the process of reduction i. e loss of election and gain of electrons occured simultaneously.

During the process of electrolysis, there is oxidation of an ion at anode which is the negative charged electrode, reduction as well takes occur at cathode which is the positively charged electrode at the same time.

In both types of voltaic and electrolytic cells the redox process that takes place at the anode is oxidation while the redox process that takes place at the anode is reduction

Explanation:

Electrons flow from the anode, the negative electrode to the cathode, the negative electrode.

Since oxidation involves the loss of an electron, therefore, oxidation takes place at the anode. Conversely, since reduction involves the gaining of an electron, the redox reduction process takes place at the cathode.

The cathode and anode form the electrodes in the voltaic cell through which electrons flow from one half cell, the anodic cell, to the other half cell, the cathodic cell.
