Statement TypeDirection (Q. No. 25) This section is based on Statement...
Statement I: In electrorefining process cathode is made up of a pure strip of the same metal.
Statement II: Blister copper contains 50% impurities.
The correct answer is option C: Statement I is correct but Statement II is incorrect.
Explanation:
Electrorefining is a process used to purify metals that have been extracted from their ores. It is commonly used for refining copper. In this process, a strip of impure metal is used as the anode, and a pure strip of the same metal is used as the cathode. The electrolyte used is a solution of the metal salt of the metal being refined.
Statement I is correct because in the electrorefining process, the cathode is indeed made up of a pure strip of the same metal. The impure metal from the anode dissolves into the electrolyte and the pure metal is deposited on the cathode, resulting in the purification of the metal.
However, Statement II is incorrect. Blister copper is an intermediate product obtained during the extraction of copper from its ore. It is produced in a smelting furnace and contains impurities such as sulfur, iron, and other elements. Blister copper typically contains around 98-99% copper and only about 1-2% impurities, not 50% impurities as stated in Statement II.
Therefore, the correct answer is option C: Statement I is correct but Statement II is incorrect.
Statement II: Blister copper contains 50% impurities.
The correct answer is option C: Statement I is correct but Statement II is incorrect.
