Assertion : Gold is isolated from other impurities by the Arndt forre...
Assertion (A): Gold is isolated from other impurities by the Arndt Forrest cyanide process.
Reason (R): The cyanide which is used here dissolves all possible impurities.
The correct answer is option 'C', which states that Assertion (A) is true, but Reason (R) is false.
Explanation:
The Arndt Forrest cyanide process is a method used to extract gold from its ore. In this process, gold is isolated from other impurities present in the ore. However, the reason provided is not entirely correct.
Cyanide is indeed used in the Arndt Forrest cyanide process, but it does not dissolve all possible impurities. The cyanide specifically targets and dissolves gold from the ore, forming a soluble complex. This complex can then be separated from the rest of the ore using various techniques, such as filtration or precipitation.
While the cyanide does react with some impurities to form other complexes, it does not dissolve all impurities present in the ore. Some impurities may remain in the final product, depending on their nature and solubility. These impurities can be further removed through additional refining processes.
Therefore, while Assertion (A) is true as gold is indeed isolated from impurities using the Arndt Forrest cyanide process, Reason (R) is false as the cyanide used in the process does not dissolve all possible impurities.
