Assertion: Mond's process is used for the extraction of tungsten from its ore.
Reasoning: In Mond's process, tungsten oxide is reacted with hydrogen gas to obtain pure tungsten metal.
Both assertion and reasoning are correct, and the reasoning is the correct explanation of the assertion.
Both assertion and reasoning are correct, but the reasoning is not the correct explanation of the assertion.
The assertion is correct, but the reasoning is incorrect.
The assertion is incorrect, and the reasoning is also incorrect.
Answers (1)
The assertion is incorrect because Mond's process is not used for the extraction of tungsten. Instead, Mond's process is used for the purification of nickel.
Mond's process involves the purification of impure nickel by selective oxidation and reduction reactions. In this process, impure nickel is heated in a stream of carbon monoxide gas, which
forms a volatile compound called nickel tetracarbonyl . The nickel tetracarbonyl vapor is then subjected to a higher temperature where it decomposes, leaving behind pure nickel metal.
Tungsten is typically extracted from its ore through a different process, such as the scheelite or wolframite extraction process. These methods involve various steps, including crushing, grinding, concentration, and chemical treatments, to obtain tungsten concentrate or ammonium paratungstate (APT). Subsequently, tungsten metal can be obtained through further processing steps like reduction or carburization.
Therefore, the assertion is incorrect, and the reasoning is also incorrect as it does not apply to the extraction of tungsten.
