What is difference between electrolysis and electroplating?

What is difference between electrolysis and electroplating?

Electrolysis is a process, which uses a direct electrical current to break chemical compounds while Electroplating is a process that uses electrical current to reduce dissolved metal cations so that they form a coherent metal coating on an electrode.

Is electroplating a type of electrolysis?

Electroplating is a type of electrolysis. Both types use electrolytic cells. Both types use the same electrolyte to immerse both electrodes. In both techniques, the oxidation occurs on the anode whereas the reduction occurs on the cathode.

What is electrolytic plating?

Electrolytic plating is a process which requires an externally applied DC current for deposition to occur as opposed to electroless plating processes in which the deposition occurs from an autocatalytic reaction of the plating chemistry with the base material.

What is electroplating and how it cleans corroded metal?

Electroplating is the process of plating one metal onto another by hydrolysis, most commonly for decorative purposes or to prevent corrosion of a metal. There are also specific types of electroplating such as copper plating, silver plating, and chromium plating. ... The surface can be a metal or even plastic.

What is the purpose of electroplating Class 8?

Electroplating is basically the process of plating a metal onto the other by hydrolysis mostly to prevent corrosion of metal or for decorative purposes.

What are the advantages of electroplating Class 8?

(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.

Why is electroplated on iron to make cans used for storing food?

Tin cans are thin electroplated on iron. ... Because tin is less reactive than iron as it will prevent food from being poisoned.

What happens if the strength of the current used in electroplating is very high?

If the strenght of the current used in electroplating is very high, the plating may become brittle. ... Also if the current is very high the metal ions can't migrate through the solution quickly enough to keep up.

Which metal is layered on iron for conservation of food?

Tin

What are tin cans Why are they used for storing food?

Tin cans used for storing food ,are made by electroplating tin onto Iron . Tin is less reactive than iron . Thus, food does not come into contact with iron and is protected from getting spoilt.

Why are cans ribbed?

Ribbing on Tin Cans strengthens the tin. ... Furthermore, the ridges on tins allow it to expand and contract. As part of the canning process, filled cans are often heated to cook and sterilise the contents. This can build up a fair amount of pressure, and the ridges let the can handle that without splitting.
