Statement I : Cast iron is obtained by remelting pig iron with scrap iron and coke using hot air blast.
Statement II : In the extraction of silver, silver is extracted as cationic complex.
The correct answer is option C, which states that Statement I is correct but Statement II is incorrect.
Explanation:
Statement I is correct because cast iron is indeed obtained by remelting pig iron with scrap iron and coke using a hot air blast. The process of obtaining cast iron involves melting pig iron, which is a crude form of iron obtained from the smelting of iron ore, along with scrap iron and coke. Coke is a form of carbon that acts as a reducing agent, and the hot air blast provides the necessary oxygen for the combustion process. The remelting process helps in removing impurities and adjusting the carbon content to produce cast iron with desired properties.
Statement II is incorrect because in the extraction of silver, it is not extracted as a cationic complex. Silver is primarily extracted from its ores through various processes such as cyanidation, froth flotation, and smelting. In cyanidation, silver ores are treated with a dilute solution of sodium cyanide, which forms a soluble complex with silver ions. The silver cyanide complex is then precipitated and further processed to obtain pure silver. In froth flotation, silver-bearing minerals are separated from other minerals by selectively attaching to air bubbles and floating to the surface. Smelting involves heating the silver ore along with fluxes to produce a silver-rich lead bullion, which is then refined to obtain pure silver.
In conclusion, while Statement I is correct in describing the process of obtaining cast iron, Statement II is incorrect as silver is not extracted as a cationic complex.
Statement II : In the extraction of silver, silver is extracted as cationic complex.
The correct answer is option C, which states that Statement I is correct but Statement II is incorrect.
