Question

Vinay wants to remove the impurities from the copper spoon given to him. a) which application of electrolysis will be helpful for him b) explain the experimental set up of the process c) state any two reasons for coating bicycle handles with chromium metal

Answer 1

The application of electrolysis process that helps in the removal of impurities is the electro refining method.

Explanation:

• a) In the electro refining method, the impurities present in the copper will move towards and settle down on the pure copper rod hence will result in the purifying process.
• b) The experimental set up process involves the usage of a copper metal dipped in a solution along with the passage of an electric current that connects between the two copper rods. The impurities like Fe and Zn will oxidize faster in the solution and they move towards and get settled over the copper rod.
• c) The coating of the bicycle handles with chromium metal is done because the chromium metal is one which is highly corrosive in nature and helps the bicycle from the corrosion activities. In addition to this, the chromium metal has lustrous property which keeps the bicycle handles in a shiny way.
