Thise electrode is the cathode.
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 happens when sodium ions come in contact with the negative electrode in a cell used for electrolysis?
When sodium ions come in contact with the negative electrode in a cell used for electrolysis, they accept electrons and get reduced to form sodium metal. This process occurs as part of the overall electrolysis reaction, where positive ions are reduced at the negative electrode while negative ions are oxidized at the positive electrode.
What kind of material is used to make the positive electrode of a dry cell?
The positive electrode is a graphite rod (elemental carbon).
How is electrolysis of water used?
Electrolysis, passing an electric current, through water separates the water into its elements: oxygen and hydrogen. When Direct Current (DC) is used, oxygen precipitates (comes out of) the water at the positive electrode and hydrogen precipitates at the negative electrode.
What are the metal strips called that are placed in the copper compound solution during electrolysis?
The metal strips are called electrodes. The positive electrode is known as the anode, and the negative electrode is called the cathode. They are used to conduct electricity through the electrolyte solution to facilitate the electrolysis process.
What is role of graphite rod in electrometallurgy of Al?
In the electrometallurgy of aluminium, a fused mixture of purified alumina (Al 2 O 3 ), cryolite (Na 3 AlF 6 ) and fluorspar (CaF 2 ) is electrolysed. In this electrolysis, graphite is used as the anode and graphite-lined iron is used as the cathode. During the electrolysis, Al is liberated at the cathode, while CO and CO 2 are liberated at the anode, according to the following equation. If a metal is used instead of graphite as the anode, then O 2 will be liberated. This will not only oxidise the metal of the electrode, but also convert some of the Al liberated at the cathode back into Al 2 O 3 . Hence, graphite is used for preventing the formation of O 2 at the anode. Moreover, graphite is cheaper than other metals.
Which anode in electrolysis?
the anode (positive electrode) is the object that is going to be anodized. The cathode normally used is carbon rod that is inert.
What is the second best electrode material for the electrolysis of water?
Platinum is considered the second best electrode material for the electrolysis of water, after iridium. Platinum is durable, has good electrical conductivity, and is resistant to corrosion, making it suitable for electrolysis applications.
Is the electrode the metal or graphite rod in an electric cell?
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.
How could a sample gas be collected at the positive electrode when using electrolysis for copper?
To collect a sample gas at the positive electrode during electrolysis for copper, a gas collection tube can be placed directly above the positive electrode. As the electrolysis is carried out, the gas generated at the positive electrode will rise and move into the collection tube, allowing for easy sampling and analysis.
Why are substances like platinum and palladium often used for carrying out electrolysis of aqueous solutions?
that is because platinum and palladium are inert elements and they wont react with the substance deposited on the electrode.. unlike if we use carbon electrodes, carbon will react with oygen deposited on it and escape out as CO2 gas
