Question

information about electroplating

Answer 1

hello frnds
..


All types of metals, including gold, silver, tin, zinc, copper, cadmium, chromium, nickel, platinum and lead, can be offered in such a way. Electroplating is similar to electrolysis (using electricity to split a chemical solution), which is in contrast to the process by which the battery produces electrical currents.

Answer 2

$\large \text{ELECTROPLATING :-}$

⤑The process of depositing a layer of any desired metal on another material by means of electricity is called electroplating.

⤑This is the most common application of chemical effects of electric current.

$\large\text{Preparations for electroplating:-}$

⤑ Articles to be electroplated should be cleaned thoroughly with an alkali & then with dilute acid to remove dust, grease or deposit on it.

⤑Only DC is to be used.

⤑For reaction, suitable temperature is necessary around the electroplating equipment. Conduction of electricity through electrolyte increases with the rise in temperature.

$\large\text{Uses of electroplating :-}$

⤑ Electroplating is used in industry for coating metal objects with a thin layer of a desired metal.

⤑ It protects metals from corrosion.

⤑ It prevents iron from rusting.

⤑ It can make more reactive metals (like iron), less reactive.

⤑Make objects appear shiny

⤑Make objects resistant to scratches.
