(i)Explain depolarisation of leklanche cell.
(ii) Explain depolarisation of daniel cell.

Answer 1

Answer:

1. The redox reaction in a Leclanché cell involves the two following half-reactions The chemical process which produces electricity in a Leclanché cell begins when zinc atoms on the surface of the anode oxidize, i.e. they give up both their valence electrons to become positively charged Zn2+ions.
2. The Daniell cell is a type of electrochemical cellinvented in 1836 by John Frederic Daniell, a British chemist and meteorologist, and consists of a copper pot filled with a copper (II) sulfate solution, in which is immersed an unglazed earthenware container filled with sulfuric acid and a zinc electrode.
