big information about electroplating
Answers
Answer:
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.The process used in electroplating is called electrodeposition. It is analogous to a concentration cell acting in reverse.
All kinds of metals can be plated in this way, including gold, silver, tin, zinc, copper, cadmium, chromium, nickel, platinum, and lead. Electroplating is very similar to electrolysis (using electricity to split up a chemical solution), which is the reverse of the process by which batteries produce electric currents.
Electroplating is used to apply metal coating on non metallic surfaces through electro chemical processes. Electroplating forms a protective barrier, reduces friction, and prevents tarnishing to name some of its benefits.
Relying on Volta's voltaic pile as a main source of electricity, the Italian chemist Luigi Brugnatelli invented electroplating in 1805. His early attempts at electroplating evolved until he successfully plated a thin layer of gold onto silver.
Answer:
electroplating has great importance in industrial field, many things are electroplated ,By the desire for preventing from rusting,or for making things attractive.
