Which of the following is NOT involved in the extraction of metals from their ores?
Answer Details
The process of extracting metals from their ores involves various methods, including reduction with carbon, reduction with other metals, reduction by electrolysis, and oxidation with oxidizing agents. We need to identify the option that is NOT involved in the extraction of metals from their ores.
"oxidation with oxidizing agents" is NOT involved in the extraction of metals from their ores. This is because oxidation is the opposite of reduction, and the extraction of metals from their ores involves reducing the metal ions to the elemental form. In other words, during the extraction of metals, reducing agents are used to reduce the metal ions to their elemental form, whereas oxidizing agents are used to oxidize the metal ions to a higher oxidation state.
Thus, the correct answer is "oxidation with oxidizing agents" is NOT involved in the extraction of metals from their ores.
Note: The choice of extraction method depends on the reactivity of the metal and the cost of the extraction process.
