Electrolysis can be used to coat a layer of a metal on an object➜ The metal that is being used to coat should be less reactive than the object’s metal➜ The anode is made of the pure metal that is to coat the object➜ The object to be coated is taken at the cathode➜ The electrolyte is a soluble salt containing the metal ion that is to coat the object➜ The pure metal loses electrons at the anode; ions go into the solution, the ions gainelectrons at the cathode and form a layer over the object➜ Electroplating is used to make objects more resistant to corrosion or to make them shinierand improve their appearance15

Which metal gets coated during electroplating?A.The metal with electrons flowing from itB.The metal that is the anodeC.The metal with ions coming off itD.The metal that is the cathode

Write short notes on (i) Anodizing, (ii) Electroplating.

Write two applications of electroplating

Assertion (A): Metal ions must be present in a solution used for electroplating a particularmetal.Reason (R): Electroplating occurs only on anode.

The set up below shows the process of electroplating of an article with silver. [ 51Electroplating is the process of depositing a thin layer of a superior metal(such as nickel, gold or silver) on the clean surface of a baser metal(such as copper or iron) by the process of electrolysis.Nandini wanted to electroplate her bracelet with silver.a) Name the electrolyte she should use.b) Write the reaction taking place at cathode.c) State the observation at anode.d) What will Nandini observe if she interchanges the terminals to which the braceletand silver plate are connected? Justify your answer.
