Tt depends on the metal which is the cathode and which is the anode. However, in most cases, graphite is the cathode and the metal is the anode. the strictly correct answer is that BOTH the metal and the graphite rod are electrodes. You must have two electrodes minimum to create a cell.

Why is graphite used as an electroed in dry cells?
Dry cell graphite electrode when treated with permanganate can be used as a hydrogen ion sensor. where activated dry cell graphite electrode seem to be suitable as potentiometric indicator electrodes. :)
What property of graphite is used as the central rod in dry cell?
The property of graphite is the killing of many other materials of the history of the elements of the chemistry.. It is discovered by Warren Jake Mendoza. A chemist who discovered this issue.
Which metal was only discovered after the invention of the electric cell?
Aluminum is the metal that was only discovered after the invention of the electric cell. It was first extracted in 1825 using a chemical process that required electricity.
What gets reduced in a galvanic cell made with magnesium and zinc electrodes?
Mg(s)
Which electrode in the anode is galvanic cell?
Zinc is the anode.
Is the rod in an electric cell metal or graphite?
Graphite

What kind of material is used to make the positive electrode of a dry cell?
The positive electrode is a graphite rod (elemental carbon).
In a wet cell electrons move from the negative electrode to the positive electrode?
In a wet cell, such as a battery, the negative electrode is where oxidation occurs, releasing electrons. These electrons flow through an external circuit to the positive electrode. At the positive electrode, reduction occurs, and electrons are accepted back, completing the circuit.
What is oxidized in galvanic cell made with silver and nickel electrodes?
In a galvanic cell made with silver and nickel electrodes, the nickel electrode undergoes oxidation as it loses electrons, which travel through the external circuit to the silver electrode where reduction occurs. This flow of electrons generates an electric current in the cell.
What is the function of the cathode and anode electrodes in an electrochemical cell?
The cathode electrode in an electrochemical cell is where reduction reactions occur, while the anode electrode is where oxidation reactions occur. These reactions generate an electric current in the cell.
What gets oxidized in an electrolytic cell made with nickel and copper electrodes?
Cu(s)
What is the redox reaction takes place in a dry-cell battery?
In a dry-cell battery, the redox reaction that takes place involves the oxidation of zinc (Zn) at the anode and the reduction of manganese dioxide (MnO2) at the cathode. The overall chemical reaction can be represented as: Zn(s) + MnO2(s) + H2O(l) -> ZnO(s) + Mn(OH)2(s).
What is the difference between a wet cell and a dry cell?
* A "dry-cell" battery is essentially comprised of a metal electrode or graphite rod (elemental carbon) surrounded by a moist electrolyte paste enclosed in a metal cylinder as shown below. * In the most common type of dry cell battery, the cathode is composed of a form of elemental carbon called graphite, which serves as a solid support for the reduction half-reaction. * At the center of each dry cell battery is a rod called a cathode, which is generally made of metal or graphite and is surrounded by an electrolyte paste. The cathode and electrolyte paste are wrapped in paper or cardboard.
What is photogalvanic cell?
A photogalvanic cell is a type of electrochemical cell that generates electrical energy from light. It typically consists of a photoactive electrode, an electrolyte, and a counter electrode. When light is absorbed by the photoactive electrode, it initiates a chemical reaction that produces a potential difference and drives an electric current.
What property of graphite is used as the central rod in dry cell?

What is the purpose of the reference electrode?
A reference electrode is an electrode with a well-known electrode potential. Its main function is to serve as a half cell to build an electrochemical cell.
