Common metals used for cathodes include platinum, palladium, gold, and copper. In battery technology, lithium, nickel, and cobalt are frequently used in lithium-ion batteries. Additionally, lead is used in lead-acid batteries for its effective electrochemical properties. The choice of metal often depends on the specific application and desired performance characteristics.
What else can I help you with?
What forms at the cathode during electrolysis of a metal compound?
At the cathode, the metal ions in the compound gain electrons and are reduced to form solid metal atoms. This solid metal deposits on the cathode during the electrolysis process.
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.
Which metal acts as the cathode during silver plating?
Cathode, as the fork attracts silver cations (+ ions)
What metal is present at both cathode and the anode in a car battery?
Lead is the metal present at both the cathode and anode in a car battery, as it is used in both the positive and negative plates of lead-acid batteries.
What will be the products on cathode and anode during electrolysis of the solution of magnesium sulphate?
At the cathode, magnesium metal will be produced, while at the anode, oxygen gas will be produced. This is because during the electrolysis of magnesium sulfate, magnesium ions will be reduced at the cathode to form magnesium metal, and water molecules will be oxidized at the anode to form oxygen gas and hydrogen ions.
What forms at the cathode during electrolysis of a metal compound?
At the cathode, the metal ions in the compound gain electrons and are reduced to form solid metal atoms. This solid metal deposits on the cathode during the electrolysis process.
Do metals form at the anode or cathode?
Metals typically form at the cathode during electrolysis. This is because positively charged metal ions are attracted to the negatively charged cathode where they gain electrons and deposit as solid metal.
What happens at the cathode in an electrolytic cell?
Reduction occurs at the cathode in an electrolytic cell.
When molten sodium chloride is electrolysed the product at cathode is?
sodium metal is deposited at the cathode.
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.
Where does reduction occur in an electrolytic?
Cathode
Where did the electrons from cathode ray come from?
In a cathode ray tube (CRT), the particles, which are electrons, originate at the heated cathode, becoming the so-called cathode rays. The electrons stream off the cathode and rush over to the anode.
Which metal gets coated during electroplating?
The cathode gets coated during electroplating.
How is the metal used in an anode different from the metal used in cathode?
copper-zinc
Which metal acts as the cathode during silver plating?
Cathode, as the fork attracts silver cations (+ ions)
Difference between direct and indirect cathode ray?
In a directly heated cathode, the filament is the cathode and emits the electrons. In an indirectly heated cathode, the filament or heater heats a separate metal cathode electrode which emits the electrons.
What is the process of electrorefining?
In an electro-refining system the deposited metal is collected without the need to remove the cathode from the slurry bath. The cathode has a hollow cavity permitting steam or hot water to be introduced to heat the cathode. During the deposition process, the heating of the cathode encourages the deposition process. When the deposited material is to be collected, the cathode is heated to "melt" the bonds between the cathode and the deposited metal. Using a bracket which was installed before the deposition process and into which the deposited metal has been formed; the now-released sheet of deposited metal is easily removed.
