It is analogous to a galvanic gll acting in reverse. Jewelry and silverware can be silver- or … 9. The same electroplating or electrodeposition principle is used in this case. Thank you, Your email address will not be published. Ferric chloride is also popular for the etching of Nimonic alloys. Cathode: The Metal to be plated by another metal Anode: The metal to be plated on Cathode Electrolyte: Conducting solution containing metal ions in which Anode and Cathode are placed. The process of depositing a thin layer of a desired metal over a metal object with the help of electric current is called electroplating. Besides, electroplating has a plethora of other applications in many industries. Electroplating is essentially a chemical reaction which helps to make various items we see and use every day. Electroplating is the process of depositing a thin film of one metal over another metal by passing electric current through an electrolyte. It is also used to protect metals susceptible to corrosion. The process used in electroplating is called electrodeposition. NCERT Textbook Solutions 2020-21 as well as Offline Apps class 8 of other subjects are also available for academic session 2020-2021.

God bless you as you effect the correction. The process used in electroplating is called electrodeposition. Less expensive metal are electroplated with more expensive metals like silver and gold to make Jewellery or ornaments. This causes the size of the anode to decline. Nickle is used in decorative items, cars, and machinery parts. Electroplating is a process that uses electrical current to reduce dissolved metal cations so that they form a coherent metal coating on an electrode 4. Electrolysis is used for the extraction of metals from its ores. 2. It is one of the most common applications of chemical effects of electric current. Using electricity, you can coat the metal of one electrode with the metal of the other with an electroplating process, also known as electrochemistry! Description. Mass plating is one of the most common types of electroplating and is one of the processes with the maximum applications. 2)Immerse the clean iron key also in copper sulphate solution at a small distance from the copper plate. Electroplating. 3)Electroplating is used to give objects made of a cheap metal coating of a more expensive metals to make them look more attractive. Question 4 Which is the polluting waste generated by electroplating factories? The added metal has a desired property the original object lacks and is primarily used to improve corrosion resistance. Answer: Applying a layer of gold on any material by electroplating is called gold plating. Electroplating is used in various commercial appliances. A combination of cells is known as _____ . The transport barrier limits the chemical transport (via diffusion and/or … Applications of Electroplating Class 8 Physics Chemical Effects of Electric Current Artificial jewelry , usually made of less expensive metals is often plated with a thin layer of a precious metal like gold and silver to make it more lustrous, appealing but cheaper. It is a matter of fact that yes - some metals are way more expensive, rare, … but being costly is deposited on materials like car parts, taps, burners, etc. Identify the electroplating process format to use based on component shape and size. or own an.
