What is electroplating give 4 examples of electroplated items?
Cutlery, kitchen utensils, pots and pans, and sink taps are a few electroplating examples which we find and use day to day. For example, silverware cutlery is electroplated to help retain its appearance and prevent tarnishing.
Electroplating is used in various commercial appliances. Nickle is used in decorative items, cars, and machinery parts. Chromium is also used in rims of wheels and zinc is also plated on various machinery parts.
Electroplating is a process that uses an electric current to reduce dissolved metal cations so that they form a thin coherent metal coating on an electrode.

1-Tin cans used for storing food are made by electroplating tin metal on to iron. 2-it is used in bicycle to resist rust or corrosion. 3-it is used in jewellery to make it lusturous. 4-it is used in LPG stoves to resist rust.
Answer: Electroplating is a method which uses electrolysis to deposit a layer of one metal on another metal. The object to be coated is made the cathode and the metal to be deposited is made the anode.
Electroplating is basically the process of plating a metal onto the other by hydrolysis mostly to prevent corrosion of metal or for decorative purposes. The process uses an electric current to reduce dissolved metal cations to develop a lean coherent metal coating on the electrode.
The different types of electroplating are: mass plating (also barrel plating), rack plating, continuous plating, and in line plating.
Electroplating involves passing an electric current through a solution called an electrolyte. This is done by dipping two electrodes into an electrolyte and connecting it to direct current.
Answer: Electroplating is a process of covering the surface of the metal with another thin layer of metal using electric current (electrolysis). Electroplating is a method to prevent corrosion of metals.
The process of depositing a thin layer of a desired metal over a metal object with the help of electric current is called electroplating. For example :Bathroom taps made of iron or steel are electroplated with chromium metal to prevent their corrosion or rusting.
What is electroplating give example?
Electroplating is the process of depositing a layer of a metal on a metallic or non-metallic electrode by electrolysis in an electrolytic cell. Let us take an iron spoon which is to be electroplated with copper.
- Tin cans used for storing food are made by electroplating tin metal on to iron.
- it is used in bicycle to resist rust or corrosion.
- it is used in LPG stoves to resist rust.
What is Electrolysis? Electrolysis is defined as a process of decomposing ionic compounds into their elements by passing a direct electric current through the compound in a fluid form. The cations are reduced at cathode and anions are oxidized at the anode.
Modern gold plating, called gold electroplating, relies on a chemical process to combine various layers of metal into a solid piece with a layer of gold resting on the surface. Electroplating has been in use commercially since the 1840s and was heavily refined during the two World Wars.
Explanation: This is done by dipping two terminal called electrodes into the electrolyte and connecting them into a circuit with a battery or other power supply .
(i) It is used to coat metal surfaces with desired metal coatings, for decoration purposes. (ii) It saves metal surfaces from rusting. (iii) It saves corrosion of surfaces of metals. (iv) Coating of chromium on metals give luster to objects.
Electroplating is the process of coating a metal with a thin layer of another metal by electrolysis to improve the metal's corrosion resistance.
The process of depositing a layer of one metal over the surface of another metal by passing electric current is called electroplating. Electroplating of metals is done to protect them from corrosion and for decoration purpose.
(a) formation of ions by two metallic plates in the acidic liquid. (b) electrodeposition of metal on electrodes. (c) electrodeposition of metal upon metallic surfaces.
If a bright and uniform appearance is desired, the lead surface can be overplated with a thin coating of bright tin or the deposit can be subsequently reflowed to a bright appearance. At the present time, Advanced Plating Technologies does not offer reflow of lead deposits.
What are metals Grade 7?
Metals are substances that form naturally below the surface of the Earth. Most metals are lustrous or shiny. Metals are inorganic, which means they are made of substances that were never alive.
When an iron object is left in damp air (or water) for a considerable time, it gets covered with a red-brown flaky substance called rust. This is called rusting of iron. During the rusting of iron, iron metal combines with the oxygen (of air) in the presence of water (moisture) to form a compound iron oxide.
Stainless steel is a metal alloy, made up of steel mixed with elements such as chromium, nickel, silicon, aluminum, and carbon. Iron is mixed with carbon to produce steel which is the main component of stainless steel. Chromium is added to make it resistant to rust. Q.
• Chemical effect of the electric current: The passage of an electric current through a conducting solution causes chemical reaction. That may cause formation of bubbles of a gas on the electrodes, deposites of metal on electrodes, changes of colour of solutions etc. •
There are several plating methods, and many variations. In one method, a solid surface is covered with a metal sheet, and then heat and pressure are applied to fuse them (a version of this is Sheffield plate). Other plating techniques include electroplating, vapor deposition under vacuum and sputter deposition.
