Write a practical to show electroplating.
Answers
Answer:
electroplating uses a form of electrolysis in which the electrodes play a bigger role than just conducting the current.
Using electricity, you can coat the metal of one electrode with the metal of the other with an electroplating process, also known as electrochemistry!
Electroplating is essentially a chemical reaction which helps to make various items we see and use every day. Jewelry and silverware can be silver- or gold-plated, while zinc is often used to coat iron to protect against rust. Professional electroplating requires specialized chemicals and equipment to make a high-quality coat, but in this project you can try your hand at a simple procedure that will transfer copper (a versatile, naturally-occurring metal) to a brass key.
