FAQs on Electrolytic Refining Video Lecture - Chemistry Class 12 - NEET
| 1. What is electrolytic refining? |  |
Ans. Electrolytic refining is a process used to purify metals by using an electrolyte solution and an electrical current. It is commonly used to refine copper, zinc, nickel, and other metals. The impure metal is dissolved in the electrolyte, and as the electric current passes through the solution, the pure metal is deposited on the cathode.
| 2. How does electrolytic refining work? | |
Ans. In electrolytic refining, a metal impure with various impurities is made the anode, and a thin sheet of pure metal is made the cathode. Both the anode and cathode are placed in an electrolyte solution. When an electric current is passed through the solution, metal cations from the anode move towards the cathode. The impurities settle at the bottom of the electrolyte, and the pure metal is deposited on the cathode.
| 3. What are the advantages of electrolytic refining? | |
Ans. Electrolytic refining offers several advantages. Firstly, it allows for the production of high-purity metals, which are essential for various industrial applications. Secondly, it can remove impurities that are difficult to eliminate through other refining methods. Additionally, electrolytic refining is a flexible process that can be used for refining multiple metals. Lastly, it is an environmentally friendly process as it minimizes the release of harmful byproducts.
| 4. What are the limitations of electrolytic refining? | |
Ans. Despite its advantages, electrolytic refining has some limitations. One limitation is the high energy consumption associated with the process. The electrolysis requires a significant amount of electricity, making it energy-intensive. Additionally, the process may not be suitable for refining metals with high melting points or those that are highly reactive. It is also a time-consuming process, which may affect the overall production efficiency.
| 5. What are some applications of electrolytic refining? | |
Ans. Electrolytic refining finds applications in various industries. One of the major applications is in the production of high-quality copper, which is used in electrical wiring, electronics, and construction. It is also used in refining metals like zinc, nickel, and silver. Additionally, electrolytic refining plays a crucial role in the manufacturing of semiconductors, jewelry, and other metal products that require high purity levels.
