In electroplating of chromium, the anode is typically made of a different material, such as lead or stainless steel, rather than chromium itself. This is because using chromium as the anode would result in the dissolution of the anode material into the electrolyte, which could lead to inconsistencies in the plating process and contamination of the deposited layer. Additionally, anodes are often designed to provide a stable and controlled environment for the electroplating reaction, which is better achieved with materials that do not dissolve under the plating conditions.
What else can I help you with?
What alloy is nichrome made of?
nichrome alloy is made by mixing up of the metals nickel and chromium.
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.
What is the chemical make up of hexavalent chromium?
It is a valence of chromium. The hexavalent chromium is present in anions as CrO42- and Cr2O72-.
List that articles which are made up of alloys used at home?
Stainless steel cookware: made up of a combination of metals like iron, nickel, and chromium. Brass doorknobs and fixtures: made of copper and zinc alloys. Aluminum foil: made from aluminum alloy. Bronze sculptures or decorations: made of copper and tin alloy.
Where do the electrons enter an electrochemical cell?
Electrons enter an electrochemical cell through the anode. The anode is where oxidation occurs, leading to the release of electrons that flow through the external circuit to the cathode.
Why anode is made up of antimonial-lead instead of Cr in Cr plating?
Anodes are made from antimonial-lead instead of chromium in chromium plating due to the electrochemical properties of lead alloys, which provide better conductivity and corrosion resistance in the plating process. Antimonial-lead anodes are also more stable and less prone to passivation compared to chromium, ensuring a consistent and efficient release of metal ions during plating. Additionally, lead alloys are more cost-effective and easier to work with than chromium, making them a practical choice for anode materials.
Anode current in an thyristor is made up of?
Holes and electrons

Are there any other names for the ruby?
no there is no other names for ruby in English. ruby is a mineral made up of aluminum oxide with chromium.
What is the chemical make up of hexavalent chromium?
It is a valence of chromium. The hexavalent chromium is present in anions as CrO42- and Cr2O72-.
How is chromium made?
Chromium is typically obtained through the mining and extraction of chromite ore. The ore is processed to extract chromium by either using the traditional method of roasting and leaching, or modern techniques such as aluminothermic reaction or electrolysis. The extracted chromium is then further processed and refined to the desired form for use in various industries.
Explain the process of electroplating of copper?
metal ions form a solid layer on a metal cathode
Is copper an anode or cathode?
In a galvanic cell or electrolytic cell, the copper can serve as either an anode or cathode depending on the specific set-up and reaction conditions. An anode is where oxidation occurs, while a cathode is where reduction occurs.
Is CrO2 an ionic or covalent bond?
Chromium oxide (Cr2O3) is an ionic compound, since it is made up of a metal and a nonmetal.
What happens to voltage as you move the anode and cathode closer in a fruit battery?
the voltage will go down when the anode and cathode are closer together but will go up when they are further apart
Why anode is eaten up in electrorefining process?
In electrolytic refining,anode contains the impure aopper and when current passes through solution all the impure copper ions from anode dissolve in solution and thus when all ion discharge anode becomes empty and thus eaten up.
