the answer is D
we have two types of reduction
electrolytic reduction and chemical reduction
electrolytic reduction is for very reactive metals like sodium potassium and so on
chemical reduction is for moderately reactive metals like zinc, iron and so on
If there's is a mistake please don't hesitate to tell me
option D is correct, because reactive metals are extracted from there ore normally by electrolytic reduction
The most common process in the extraction of metals from their ores depends on the reactivity of the metal. For metals that are less reactive than carbon, such as zinc, iron, tin, lead, and copper, reduction with carbon can be used to extract the metal from its ore ². For very reactive metals, electrolysis is used to extract the metal from its ore ⁴. So in this case, the most common process would be **D. reduction**.
The correct answer is B
, electrolysis. Electrolysis is a process that uses electricity to separate substances. In the extraction of metals, electrolysis is used to separate the metal from its ore. The metal ore is placed in a solution, and an electric current is passed through it. The metal ions are attracted to one electrode and the oxygen ions are attracted to the other. This allows the metal to be separated from the oxygen. Some examples of metals that are extracted by electrolysis include aluminum, magnesium, and sodium.
i also think the answer is b but i dont want to learn something wrong pls what's the right answer????
The right answer is B
electrolysis is main common method for extraction of metals.... during electrolysis, oxidation and reduction occurs at the anode and cathode
