FAQs on Electrolytic Refining of Metals Video Lecture - Class 10

1. What is the process of electrolytic refining of metals?

Ans. Electrolytic refining is a process used to purify impure metals by passing an electric current through a solution of the metal's salt. This process involves two electrodes, an impure metal as the anode and a pure metal as the cathode. As the electric current passes through the solution, the impure metal is gradually dissolved from the anode and deposited as a pure metal on the cathode.

2. Why is electrolytic refining used for metal purification?

Ans. Electrolytic refining is preferred for metal purification because it allows for the removal of impurities with high precision. By controlling the electric current and other factors, specific impurities can be selectively removed from the metal. This process also allows for the production of high-quality, pure metals that meet industry standards.

3. What are the advantages of electrolytic refining over other refining methods?

Ans. Electrolytic refining offers several advantages over other refining methods. Firstly, it allows for the purification of metals to a higher degree of purity. Secondly, it is a precise method that can remove specific impurities. Thirdly, it is a cost-effective process that can be scaled up for large-scale metal production. Lastly, it is an environmentally friendly process as it does not generate harmful byproducts.

4. Which metals are commonly refined using the electrolytic refining process?

Ans. The electrolytic refining process is commonly used for refining metals such as copper, gold, silver, and nickel. These metals are often found in impure forms and need to be purified for various industrial applications. The electrolytic refining process ensures the production of high-quality metals suitable for their respective uses.

5. What are the steps involved in the electrolytic refining of metals?

Ans. The steps involved in the electrolytic refining of metals are as follows: 1. Dissolution: The impure metal is made the anode and immersed in an electrolyte solution containing a salt of the metal. 2. Electrolysis: An electric current is passed through the electrolyte solution, causing the metal to dissolve from the anode and move towards the cathode. 3. Deposition: The metal ions reach the cathode and get reduced, depositing pure metal on the cathode. 4. Collection: The pure metal deposited on the cathode is collected and further processed to obtain the final product.

Our topic for today is Electrolytic Refining of Metals.
Nice Jacket.
Thank you.
Hey. My Jacket.
Our last participant is Mr. Smart.
Electrolytic refining is the process of obtaining pure metals like gold, silver, copper etc. by the process of electrolysis.
Electrolytic refining of copper.
Take an electrolyte of acidified copper sulfate solution.
Take the anode as a thick rod of impure copper and the cathode as a thin rod of pure copper.
There are so many people here.
Hey.
Give me my jacket.
Current is passed through the solution, as a result the acidified Copper Sulfate electrolytic solution splits into copper ions and sulfate ions.
The copper ions from the electrolyte get attracted towards the cathode.
The copper ions gain 2 electrons from the
cathode and deposit as pure copper atoms on the thin copper rod.
At the same time, the copper atoms from the anode lose 2 electrons, get converted into copper ions and dissolve in the electrolytic solution.
Thus, the concentration of the electrolyte remains the same.
In this way, indirectly, copper atoms from
the anode get deposited on the cathode repeatedly.
Hence, eventually size of the anode decreases and size of the cathode increases.
The reactions that take place at the anode and cathode are as follows.
In this way, all the pure copper from the anode deposits on the cathode.
The impurities in the impure copper rod settle down as anode mud at the bottom of the container.
