Electron flow is from anode (+) to cathode (-)
In an electrolytic cell
An electrolytic cell
Electrons flow in the opposite direction.
Electrolytic cell
A galvanic cell can become an electrolytic cell by applying an external voltage that is of opposite polarity to the cell's spontaneous voltage. This external voltage can overcome the natural tendency of the cell to generate electricity and drive a non-spontaneous chemical reaction in the reverse direction, converting it into an electrolytic cell.
In an electrolytic cell
The significance of anode polarity in electrochemistry is that it determines the direction of electron flow in a galvanic cell or electrolytic cell. The anode is where oxidation occurs, and it is positively charged in a galvanic cell and negatively charged in an electrolytic cell. This polarity affects the overall reaction and the flow of ions in the cell.
Reduction occurs at the cathode in an electrolytic cell.

In an electrolytic cell, the anode is positive.
A cation. A positively charged ion that is attracted towards the cathode in an electrolytic cell.
In an electrolytic cell, the anode is designated as positive.
