Question

extraction of highly reactive metal with details class 10 cbse.
only detailed answer will be marked as Brainliest. if you don't know then don't answer. ​

Answer 1

Explanation:

Highly reactive elements are extracted by electrolysis methods

Step 1 - the ore should be melted first and anode and cathode should be dipped in it

Step2- electricity should be passed though it

Step3- the metal would be found on the cathode as cathode is negative and attracts the metal due to its positive valency

Srep4- the metal should be refined

then we get pure extracted metal!!!

Answer 2

Answer:

sodium:-

Explanation:

ORE:-ROCKSALT -Nacl

sodium is extracted by the electrolytic reduction of molten Nacl

when electric current is passed through molten Nacl,it splits up into Nacl+ and Cl- ion.

when electricity is passed through electrolyte Na+ ions go to the cathode where as Cl+ ions are liberated at anode.

AT CATHODE:

Na+ + e- gives rise to Na .

AT ANODE:

Cl- - e- gives rise to Cl

Cl +Cl gives rise to Cl2 gas
