Question
The method used to extract a metal is dictated by Athe position of the metal in the periodic table Bthe position of the metal in the electrochemical series Cthe melting point of the metal Dthe electrical conductivity of the ore of the metal
Solution
The correct answer is B. the position of the metal in the electrochemical series.
Explanation:
The method used to extract a metal from its ore depends on the reactivity of the metal, which is determined by its position in the electrochemical series.
Metals that are less reactive, such as gold and silver, can be found in their native state and require little to no extraction process.
Metals that are more reactive, such as aluminium and potassium, cannot be extracted from their ores by simple reduction reactions. They require more energy-intensive methods such as electrolysis.
The position of the metal in the periodic table, the melting point of the metal, or the electrical conductivity of the ore do not directly dictate the method used for extraction.
