How can a galvanic cell become 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.
How can a galvanic cell become an electrolytic?

How can galvanic cell become and electrolytic cell?
A galvanic cell can become an electrolytic cell by applying an external voltage greater than the cell's electromotive force (EMF). This reverse process forces the spontaneous redox reaction to go in the opposite direction, causing the cell to consume electrical energy to drive a non-spontaneous reaction. Essentially, the galvanic cell, which generates electricity from chemical reactions, can be converted into an electrolytic cell that requires electricity to induce chemical changes. This transformation is commonly seen in processes like electrolysis.
How is an electolytic cell different from a galvantic cell?
In an electrolytic cell, electrical energy is used to drive a non-spontaneous reaction, causing a chemical change. In contrast, a galvanic cell generates electrical energy from a spontaneous chemical reaction. Electrolytic cells are often used in processes like electrolysis, while galvanic cells are used in batteries.
Why cathode is positive in electrochemical cell but different in electrolytic cell?
In an electrochemical cell (galvanic cell), the cathode is positive because it is where reduction occurs, attracting cations from the electrolyte. Conversely, in an electrolytic cell, the cathode is negative because it is connected to the external power source, which forces electrons into the electrode, facilitating reduction at that terminal. Thus, the polarity of the cathode changes depending on the type of cell and the direction of the current flow.

What is the significance of anode polarity in electrochemistry?
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.
