The two most common materials used to make anodes are graphite and metals such as zinc, aluminum, or magnesium. Graphite anodes are often used in applications where high levels of electrical conductivity and chemical resistance are required, while metal anodes are typically used in sacrificial anode systems to protect steel structures from corrosion.

What happens to the mass of the metal anode as the cell continues to operate?
As the cell operates, the metal anode loses mass due to oxidation as it gives away electrons. This process results in the anode material dissolving into the electrolyte solution.
In the production of anode rays why perforated cathode plate is used?
A perforated cathode plate is used in the production of anode rays to allow some electrons to pass through and create a beam of electrons. This helps in generating a focused and directional electron beam for studying the properties of anode rays. The perforations also provide a way for the electrons to accelerate towards the anode, contributing to the formation of anode rays.
Which anode in electrolysis?
The anode in electrolysis is the positive electrode where oxidation occurs. This means that electrons are released from the anode, causing ions to be attracted towards the cathode for reduction.
What is the direction electron flow during the x ray exposure?
During X-ray exposure, electrons flow from the cathode to the anode in the X-ray tube. This flow of electrons generates X-rays by interacting with the anode target material, producing high-energy photons that are used for imaging purposes.
Can an anode be dug up and moved?
Yes, an anode can be dug up and moved if necessary. Anodes are sacrificial components used to protect metal structures from corrosion, so if the anode is not effectively protecting the structure in its current location, it can be relocated to improve its effectiveness.
Is anode the electron-providing electrode?
Yes, anode the electron provides electrode. It is stated that an electrode is a conductor that is used to make contact with non-metallic parts of a circuit.
What is a sacrificial anode and how does it protect galvanized pipe?
A sacrificial anode is used to send stary current to ground through the anode. This wiil cause the anode to be eaten away saving the pipe from this effect. If you put two dissimilar metels together like brass and iron, it can make a weak battery and make a current. Some soils or other environments can cause this effect.
Difference between rotating anode x ray tube and stationary x ray tube?
A rotating anode promotes cooling between exposures by distributing the intense beam from the cathode over the surface of the anode. A rotating anode tube lasts a lot longer than a stationary x-ray tube.
What are the cathode and anode in a fuel cell made from?
The cathode in a fuel cell is typically made from a material like platinum, which serves as a catalyst for the oxygen reduction reaction. The anode is usually made from a material like nickel, which helps facilitate the oxidation of the fuel.
Why would you not have an anode rod?
Anode rods are used in RV and home hot water heaters. Aluminum tanks are not required to have an anode rod where steel tanks usually are.
What happens to the mass of the metal anode as the cell continues to operate?
As the cell operates, the metal anode loses mass due to oxidation as it gives away electrons. This process results in the anode material dissolving into the electrolyte solution.
What is the gas liberated at anode in the manufacture of caustic soda using nelson cell?
The raw material for the manufacturing of caustic soda is sodium chloride so gas liberated at anode is chlorine.
What is an anode made from?
Anode is the negative terminal of a battery. It is made of Tungsten which is the same metal used in the filaments of bulbs.
What is velour material?
Velour material is material used to make tracksuits etc.
Can you call forward bias voltage as positive voltage?
it is not necessary that always positive voltage should act as a forward bias voltage , it is the potential difference between cathode and anode that makes it forward or reverse biased .it the anode(p- doped material) positive with respect to cathode(n- doped material) --> forward biasedit the anode(p- doped material) negative with respect to cathode(n- doped material) --> reverse biasedex.anode - 5v cathode - 3vanode - 1v cathode - -2vboth the examples are forward biased.
In the production of anode rays why perforated cathode plate is used?
A perforated cathode plate is used in the production of anode rays to allow some electrons to pass through and create a beam of electrons. This helps in generating a focused and directional electron beam for studying the properties of anode rays. The perforations also provide a way for the electrons to accelerate towards the anode, contributing to the formation of anode rays.
What types of anode?
the two types of anode is stationary anode and rotating anode
