Question

collect the information about electroplating make a list of articles in day to day life where this technique is used​

Answer 1

HEY!!!! here is your answer :)

Electroplating is an art of protecting metal surface form corrosion and giving it pleasant appearance. A crude metal is likely to get corroded or affected in the environmental condition, which is why electroplating is used. It is application of metallic coatings on metallic or non-metallic surfaces through electrolysis. Electroplating apart from improving aesthetics of metals also brings about change in its physical, chemical and mechanical properties. It has wide range of applications starting from protection to many industrial uses.

Uses:)

Electroplating is used to coat a surface with a thin layer of metal through electrochemical processes. As students, we may remember such demonstrations from science class, in which electroplating was used to illustrate the chemical principles underlying the process, but the technique has many practical applications

The object to be plated is placed in a solution containing ions of the metal with which it is to be plated. When a negative charge is applied to the object, the positively charged metal ions are attracted to it. When these ions touch the negatively charged object, the ions are chemically reduced, meaning they become neutral. No longer charged, they become insoluble, precipitating as solid metal, in a very thin coat on the object that is being plated

Some metals are considered far more attractive and valuable than others, gold and silver being the oldest and most obvious examples. But gold and silver are rare and expensive. Through electroplating, a very thin layer of gold or silver can coat a less valuable metal, making a final product with all the luster and beauty of those rare metals, at a fraction of the cost. This was the first commercial application of electroplating, and has been in use since the early 1800s. Thin layers of chromium are often used on appliances and automobiles to produce a pleasant, shiny appearance.
