Where does reduction occur in an electrochemical cell?
The cathode.
In the electrolytic cell electron flows from?
Electron flow is from anode (+) to 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?
cathode
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.
What happens in the cathode in an electrolytic cell?
Reduction occurs at the cathode in an electrolytic cell.
In the electrolytic cell electron flows from?
Electron flow is from anode (+) to cathode (-)
Where does reduction occur in an electrolytic cell?
The electrode where reduction occurs
What would be the cathode in a magnesium and zinc galvanic cell?
In a galvanic cell, the less reactive metal is the cathode, where oxidation takes place. In this case the cathode is zinc.
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.
Where does reactions occur in a electrolytic cell?
In an electrolytic cell
What is the negative electrode of a voltaic cell called?
This is the anode.
Which electrode of a voltaic cell the cathode or the anode corresponds to the higher potential energy for the electrons?
Cathode
What gets heavier and electrochemical cell?
The cathode
