Given below are two statements.
Statement-I: During electrolytic refining, blister copper deposits precious metals.
Statement-II: In the process of obtaining pure copper by electrolysis method, copper blister is used to make the anode.
In the light of the above statements, choose the correct answer from the options given below.
Given below are two statements.
Statement-I: During electrolytic refining, blister copper deposits precious metals.
Statement-II: In the process of obtaining pure copper by electrolysis method, copper blister is used to make the anode.
In the light of the above statements, choose the correct answer from the options given below.
- Both Statement-I and Statement-II are true.
- Both Statement-I and Statement-II are false..
- Statement-I is true but Statement II is false..
- Statement-I is false but Statement-II is true
The Correct Option is A
Solution and Explanation
The correct option is(a): Both Statement-I and Statement-II are true.
Copper is refined using an electrolytic method. Anodes are of impure copper and pure copper strips are taken as cathode
Impurities from the blister copper deposit as anode mud which contains antimony, selenium, tellurium, silver, gold and platinum.
Hence both statements are true

Occurrence of metals
The existence of metals often plays an important role in our survival, even if we are unaware of them. Our reliance on metals has been strong since the old industrial era. From buildings to jewelry, we utilize them for everything. But where do we acquire these metals from and how are they made? Let's read the occurrence of metal in more detail.
Metals are found in the earth's crust, and it seems to be a good place to extract them through various processes such as metallurgy. The process of extracting metals from ores is called metallurgy. Mining is the most common method of extracting metals from the earth.
In nature, metals are mostly found in mixed conditions. However, they can also be found in a free state. In its natural state, a native metal is one that can be found in its pure form or as part of an alloy. Most metals are exposed to natural processes such as oxidation and corrosion. As a result, only non-reactive metals such as gold, silver, platinum, and others are discovered in their native or open-free condition. Most metals are obtained as compounds, which must be filtered to remove contaminants before being employed in numerous applications.
