Take a copper sulphate solution in a beaker . Connect an iron nail that to be electroplated to the negative terminal of a battery . Connect a copper strip to the positive terminal of the battery . Dip the copper strip and object to b electroplated in the beaker containing copper sulphate solution .Leave the set up for half an hour . U will c a deposit of reddish broun coating on the object . When electricity is passed through the solution , copper ions move towards the cathode and get reduced to copper metal . This metal gets electroplated on the object .Electroplating The most common application of electrolysis is electroplating. Electroplating is a process of coating one metal with another using an electric current. In this process, there exists an electrolyte, through which current passes
