Question

a metal m is found a form of sulpher m2s and is good conductor of electricity. and it uses in making wires identify the metal m and write the stels involved extraction of these metal​

Answer 1

Hey there,

● Answers -

(i) Copper.

Copper is used to make electric wires and usually found as sulphide ore Cu2S.

(ii) Roasting -

Copper is extracted from its sulphide ore by roasting.

2Cu2S + O2 ---> 2Cu2O + 2SO2

2Cu2O + Cu2S ---> 6Cu + SO2

(iii) Electrolytic refining of copper -

- It involves electrolysis of copper sulphate solution with copper electrodes.

- It involves impure copper anode and pure cooper is deposited at cathode.

At anode, Cu ---> Cu2+ + 2e-

At cathode, Cu2+ + 2e- ---> Cu
