Question

a small amount of copper can be obtained from copper sulphate solution by which reaction​

Answer 1

Answer:

By electrolysis process...

Explanation:

by this process ions migrate from anode to cathode and a layer copper sulphate is formed on anode

Answer 2

A small amount of copper can be obtained from copper sulphate solution by these reaction :-

CuSO4(aq) + H2(g) ---(Q)--> Cu(s) + H2SO4(aq) (  T=150 °C,)

We must drop the solution of copper sulphate in a closed container and pressurize it with hydrogen gas. After, we heat it at 150 °C for 1 hour. Copper (Cu2+) from copper sulphate will precipitate as copper powder (Cu).
