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.

Question

Study the reaction scheme shown below and identify the reactants A, B and C.

Answer 1

To solve the given question, let's analyze both the statements regarding copper refining by the electrolytic process.

Statement-I: During electrolytic refining, blister copper deposits precious metals.

Explanation: In the electrolytic refining of copper, blister copper (which contains impurities, including precious metals like gold and silver) is used as the anode. During the process, copper ions from the anode dissolve into the electrolyte solution and get deposited on the cathode as pure copper. The precious metals do not dissolve and hence settle down as anodic sludge or slime. This residue is then processed further to recover precious metals.

Conclusion: This statement is true as it correctly explains that precious metals are deposited as a result of a different process in electrolytic refining.

Statement-II: In the process of obtaining pure copper by the electrolysis method, copper blister is used to make the anode.

Explanation: In electrolytic refining, blister copper is indeed used to make the anode. The impure copper acts as the anode, and pure copper is deposited on a starter sheet of pure copper acting as the cathode.

Conclusion: This statement is true as it correctly states the role of blister copper in the electrolysis process.

Conclusion of Both Statements: Both statements are true. Statement-I correctly describes the deposition of precious metals and Statement-II accurately states the use of blister copper as the anode in electrolytic refining.

Correct Answer: Both Statement-I and Statement-II are true.
