How is the method of extraction of metal high up in the reactivity series different from that for metals in the midle?

Question

Answer

High reactive series metal are extracted through electrolysis whereas middle reactive metal are exctrated through calcination or roasting

Answer

Hi, I some what didn't understand your question.But here's my answer for that
Very reactive Metals like Sodium, pottasium, calcium,magnesium, aluminum and zinc can are extracted by process of electrolysis. But they cannot be reduced.

Where's the less reactive metals like iron, lead, copper, mercurry and silver can be reduced, so the refore they follow the process of calcination and reduction.

And also metals like the Gold and Platinum have no reaction, least reactive metals, i.e. they are occurring in native state(free state). No need to be separated or extracted.
I think i am somewhat correct, but i may be wrong. Ask your dobuts to your classmates for more clarification.
Thankyou, hope it helps.

Yes, reactive metals doesn't found free in natue, thus are only electrolyted. Less reactive metal are in native state, therefore extracted by reduction.

Answer

Extraction of Metals High up in the Reactivity Series

The method of extraction of metals high up in the reactivity series differs significantly from that of metals in the middle. This is primarily due to the difference in the chemical properties and reactivity of these metals.

Chemical Properties:
Metals high up in the reactivity series, such as sodium, potassium, and calcium, have a strong tendency to react with oxygen and water. They are highly reactive and easily lose electrons to form positive ions. On the other hand, metals in the middle of the reactivity series, such as iron, zinc, and copper, are less reactive and do not readily react with oxygen or water.

Method of Extraction:

Metals High up in the Reactivity Series:
1. Electrolysis: The extraction of metals high up in the reactivity series, particularly those from sodium to aluminium, involves the process of electrolysis. In this method, an electrolyte, usually a molten salt or an aqueous solution of the metal salt, is used. The metal compound is dissolved in the electrolyte, and when an electric current is passed through the electrolyte, the metal ions migrate towards the cathode and gain electrons to form the pure metal.
2. Reduction with Carbon: Some metals, such as zinc, iron, and lead, which are high up in the reactivity series, can be extracted by reducing their oxides with carbon. The metal oxide is heated with carbon, usually in the form of coke or charcoal, in a furnace. The carbon displaces the metal from its oxide, resulting in the formation of carbon dioxide and the pure metal.

Metals in the Middle of the Reactivity Series:
1. Reduction with Carbon: Metals in the middle of the reactivity series, such as iron, zinc, and copper, can be extracted by reducing their oxides with carbon. The metal oxide is heated with carbon in a furnace, and the carbon displaces the metal from its oxide, resulting in the formation of carbon dioxide and the pure metal.
2. Electrolysis: Some metals, such as copper and zinc, can also be extracted by electrolysis. In this method, the metal compound is dissolved in an appropriate electrolyte, and an electric current is passed through the solution. The metal ions migrate towards the cathode and gain electrons to form the pure metal.

Conclusion:
The method of extraction of metals high up in the reactivity series primarily involves electrolysis or reduction with carbon. Metals in the middle of the reactivity series can also be extracted using similar methods, but electrolysis is less commonly employed. The choice of extraction method depends on the reactivity of the metal and the chemical properties of its compounds.
