Question

Name the cell obtained by coupling zinc electrode with copper

Answer 1

Answer:

the spontaneous reaction that occurs when zinc metal is placed in a solution of copper ions as described by the net ionic equation shown below.

Cu+2 (aq) + Zn (s) -------> Cu(s) + Zn+2 (aq)

The zinc metal slowly "dissolves" as its oxidation produces zinc ions which enter into solution. At the same time, the copper ions gain electrons and are converted into copper atoms which coats the zinc metal or sediments to the bottom of the container. The energy produced in this reaction is quickly dissipated as heat, but it can be made to do useful work by a device called, an electrochemical cell.
