Question

) Find out if there is a commercial electroplating unit in your town.
What objects are electroplated there and for what purpose? (The
process of electroplating in a commercial unit is much more complex
than what we did in Activity 14.7). Find out how they dispose off the
chemicals they discard.​

Answer 1

Answers to the questions are given below.

Explanation:

• No, there is no commercial unit in my town.
• Mostly metals are electroplated but some non-metals are also electroplating. This is done to increase the resistance of that metal from the corrosion. Non corrosive metals are used for that.
• The electroplating process is done by giving pulsed electric current between the two metal surfaces which has to be fused. Oxidation process occurs between them by attracting anions.
• Waste chemicals are released during the process eg.- for copper coating on iron, sulphate is released. It depends upon the reaction and reactants used in reaction.
