Carbon rod is used to make the positive electrode of a dry cell.We can see a carbon rod part. This carbon rod forms a positive electrode. The carbon rod is coated with MnO2 and powdered carbon. The powdered carbon will reduce the internal resistance of the cell and hence the metal rod on the carbon rod also acts as a positive terminal.A standard dry cell comprises a zinc anode, usually in the form of a cylindrical pot, with a carbon cathode in the form of a central rod. The electrolyte is ammonium chloride in the form of a paste next to the zinc anode.

What material is used as the positive electrode?
The positive electrode is nickel hydroxide and the negative electrode is of iron. The active material for the latter is formed into pellets which are contained in a ‘pocket’ of perforated nickel-plated steel.
Which material is used as positive and negative terminal in dry cell?
This traditional dry cell consists of a carbon-rod cathode (positive terminal) immersed in a moist paste of MnIVO2, ZnIICl2, NH4Cl, and powdered carbon, which is contained in a metallic zinc-can anode (negative terminal).
Why graphite is used in dry cell?
Graphite is used for making electrodes in dry cells because it has the property to conduct electricity without taking part in a chemical reaction.
Why is graphite used to make dry cell electrodes?
Graphite rods are used as electrodes in electrolysis because graphite’s structure enables it to be an excellent conductor. The high number of delocalized electrons allows electricity to pass through graphite rapidly.
What is a positive electrode called?
During charge, the positive electrode is an anode, and the negative electrode is a cathode.

Why ammonium chloride is used in dry cell?
Function of ammonium chloride in dry cell batteries is to regulate the pH of electrodes by decomposing into ammonia gas and hydrogen ions. It also increases the concentration of hydrogen ions, which allows the voltage of batteries to drop.
Why zncl2 is used in dry cell?
Explanation: It is known that batteries of dry-cell consists of zinc chloride paste because zinc chloride helps the cell by providing electric power to different substances. Also, zinc chloride helps in the conduction of electricity.

Which metal layer is used for negative terminal of cell?
Zinc acts as a negative electrode as it has more negative potential and acts as the anode.
What is the negative and positive terminal of dry cell made up of Class 6?
The dry cell consists of a zinc can, electrolyte paste, and a carbon rod in the center. A chemical reaction takes place between the zinc can and the paste. Electrons flow from the negative (zinc) terminal to the positive (carbon) terminal.
In which of the following cells carbon is not used as positive electrode?
Solution : Carbon is not used as positive electrode in lead acid battery.
Why is graphite used as an electrode not diamond?
Graphite is used in making electrodes because it is a good conductor of electricity due to the presence of free electrons. One valence electron of each carbon atom remains free and thus it is a good conductor of electricity.
Why graphite is used in pencil lead?
it is a good conductor of heat and electricity.it is soft.it is highly resistant to chemicals. Solution : Graphite is used as pencil lead because it is soft and leaves an impression on the paper.
For which of the following purpose a carbon rod is used in a dry cell *?
The carbon rod in a dry cell doesn’t take part in the electrochemical reactions that occur in a cell to produce an electric current. However, the carbon rod simply allows the flow of electrons.
Why are carbon rods used as electrodes?
Carbon electrodes are used in electrolysis due to their competence as a conductor and the number of free electrons they have available for transfer. Not only is carbon an efficient conductor, it also has a very high melting point. This means it can be used to facilitate a wide range of different reactions.
What are uses of graphite?
- Refractories.
- Batteries.
- Steelmaking.
- Brake linings.
- Foundry facings and lubricants.
- Pencils.
- Other uses.
- Expanded graphite.
Is graphite inert electrode?
Graphite and platinum are examples of inert electrodes. Examples of reactive electrodes are copper, silver and gold. An example of electrolysis using inert electrodes is the electrolysis of dilute sulfuric acid using graphite electrodes for the cathode and anode.
What makes a positive electrode positive?
1. The positive electrode in an electrolytic cell, toward which negatively charged particles are attracted. The anode has a positive charge because it is connected to the positively charged end of an external power supply.

Is copper an anode or cathode?
In closed circuit, a current flows between the two electrodes. Zinc behaves as the anode (supplying electrons) of the galvanic cell and the copper as the cathode (consuming electrons).
What is an electrode that has a positive charge?
The anode is the positively charged electrode. The anode attracts electrons or anions. The anode may be a source of positive charge or an electron acceptor.
