In a Nelson cell, the cathode typically has a cylindrical shape. It is perforated to allow the efficient circulation of the electrolyte, facilitating better ionic movement and enhancing the overall efficiency of the electrochemical process. The perforations also help in maintaining uniform current distribution across the cathode surface. This design optimizes the production of chlorine and caustic soda during the electrolysis of brine.

Where does reduction occur in an electrochemical cell?
The cathode.
Where does reactions occur in a electrolytic cell?
In an electrolytic cell
Which part of a cell can be used as the site for electroplating?
The metal cathode of a cell can be used as the site for electroplating. It is where the metal ions in the electrolyte solution are reduced and deposited onto the surface of the cathode material.
In the electrolytic cell electron flows from?
In the electrolytic cell, electrons flow from the negative terminal (cathode) to the positive terminal (anode). This flow allows for the oxidation of ions at the anode and the reduction of ions at the cathode, resulting in the desired chemical reactions to occur.
How is an electrolytic cell different from a galvanic cell?
Electrons flow in the opposite direction.
Difference Downs cell and nelson cell are electrolytic cell between Daniel cell and fuel cell r galvanic or voltaic cell?
In Nelson's cell, an aqueous solution of concentrated NaCl is used for the industrial production of NaOH, while in Down's cell fused or molten NaCl is used for obtaining sodium metalIn Nelson's cell, three main chemicals are obtained as products that are Hydrogen gas, Chlorine gas and NaOH whereas in down's cell chlorine gas and sodium metal is produced as a product.In Down's cell, graphite is used as anode and iron is used as cathode. But, in Nelson's cell perforated steels is made cathode and grapite as anode.
How is sodium hydoxide manufactured by nelson's cell?
Principle of Nelson cell: Electrolyte used in this process is aqueous NaCl(Brine). Process:Nelson cell consists of a "U" shaped perforated steel tube which is quoted with asbestos in inner surface.A carbon rod suspended into it acts as cathode .The electrolyte used is brine solution.The roof of the equipment acts as anode.The asbestos lining separates the cathode and the anode.Steam is sent from the bottom. NaCl <==> Na+ + Cl- (in solution) At Cathode 2H2O+2e <==>H2 + 2OH- Na+ OH- <==> NaOH At anode 2Cl- --> Cl2 + 2e
Where does reduction occur in an electrochemical cell?
The cathode.
Is the cathode positive in a galvanic cell?
No, the cathode is negative in a galvanic cell.
What happens in the cathode in an electrolytic cell?
Reduction occurs at the cathode in an electrolytic cell.
Is the cathode negative in an electrochemical cell?
Yes, the cathode is negative in an electrochemical cell.
Is the cathode or anode positive in a galvanic cell?
In a galvanic cell, the cathode is positive.
Is the cathode positive or negative in a galvanic cell?
In a galvanic cell, the cathode is the positive electrode.
What would be the cathode in a magnesium and zinc galvanic cell?
The magnesium would be the cathode in a galvanic cell with zinc. Reduction occurs at the cathode during cell operation, and in this case, magnesium is reduced while zinc undergoes oxidation at the anode.
Where does reduction occur in an electrolytic cell?
Reduction occurs at the cathode in an electrolytic cell. This is where cations in the electrolyte solution gain electrons and get reduced, leading to the deposition of a substance onto the cathode.
What is the relationship between the cathode and anode in an electrochemical cell?
In an electrochemical cell, the cathode is where reduction occurs, while the anode is where oxidation occurs. The cathode and anode are connected by an external circuit, allowing for the flow of electrons from the anode to the cathode. This flow of electrons generates an electric current in the cell.
A voltaic cell is made with gold and sodium electrodes What happens at the cathode of this cell?
Gold is reduced. Gold is plated onto the cathode.
