FAQs
Which Of The Following Is Not Used For Electroplating Metal Articles? ›
Therefore, the metal that could not be used for electroplating through the use of an aqueous solution is (D), sodium.
Which material is not used for electroplating metal articles? ›Sodium is not used for electroplating metal articles.
Which of the following is used for electroplating metal articles? ›Electroplating is a process of metal coating on another piece of metal through an electrodeposition process. Metals commonly used in electroplating include Zinc, Copper, Tin, Chromium, Gold, Nickel, Silver, and Palladium.
Is nickel used for electroplating metal articles? ›Nickel electroplating is a technique in which a thin layer of nickel is electroplated on a metal. In this process nickel sulfate is used as an electrolyte, an article to be electroplated is placed at cathode and a block of nickel metal is used as anode.
Which of the following is not a purpose of electroplating? ›The correct answer is (c) Corrosion prevention.
The main principle behind the Electroplating is Hydrolysis. It is used in decorative purposes, in coating other metals etc. It does not helps in preventing corrosion as it is prevented by painting.
Explanation: Electroplating is the process of coating the thin layer of metals with desired metal to resist rust. Chromium metal has a shiny appearance. It is used for electroplating so that it does not corrode and resist scratches over the objects.
Why iron is not used in electroplating? ›Iron is more reactive than copper and less reactive metal cannot displace a more reactive one so , iron can't be electoplated on copper.
What are the four metals used to electroplate objects? ›Common metals used in the electroplating process include black and silver nickel, chromium, brass, cadmium, copper, gold, palladium, platinum, ruthenium, silver, tin and zinc. We typically recommend using Grade S or N Nickel, cadmium pellets, CDA 101 OFHC Copper, brass alloys, tin anodes and zinc.
Is silver used for electroplating metal articles? ›In the process of silver plating the object or an analyte which is to be plated is made from the cathode of an electrolytic cell. The anode is made up of a bar of silver metal. The electrolytic solution which is the liquid present in between the electrodes is a solution of Sodium argentocyanide.
What material is used in electroplating? ›Some of the most commonly used metals for electroplating include: Copper: Copper is often used for its conductivity and heat resistance. It is also commonly used to improve adhesion between layers of material. Zinc: Zinc is highly corrosion-resistant.
Is zinc used for electroplating iron objects? ›
However, iron tends to corrode and rust. So, a coating of zinc is deposited on iron to protect it from corrosion and formation of rust.
Is nickel good for electroplating? ›Electroplated nickel is used extensively to enhance the utility, value and appeal of manufactured products such as consumer goods. Other nickel coatings are used to improve the physical properties such as resistance to wear, heat or corrosion.
Why silver nitrate is not used for electroplating? ›Silver nitrite is not used as electrolyte for electroplating with silver because the deposition of silver will be very fast and hence not very smooth and uniform.
Why is zinc not used for electroplating? ›Zinc plating cannot withstand temperatures that exceed 500°F because its protective corrosion ability begins to decrease if the temperature exceeds 212°F. Generally, zinc plating should not be done if it is exposed to temperatures that exceed 500°F.
Which one is not an objective of electroplating on metals? ›Explanation: Electroplating is the process by which a metal gets deposited over the other in the presence of metal salt (in aqueous solution). Hence it is used in decorative purposes, in coating other metals etc. It does not help in preventing corrosion (painting helps in preventing corrosion).
What is electroplating questions and answers? ›Electroplating is the process of depositing a layer of any desired metal on another material by means of electricity. Q. The process of depositing a layer of any desired metal on another material by means of electricity is called electroplating.
