Question

(a) Draw the labelled diagram of Daniell cell.
(b) Write the half-reactions of oxidation and reduction taking place on electrodes.

Answer 1

(a) The labelled diagram of Daniell cell is as shown.
(b) The half-reactions of oxidation and reduction taking place on electrodes are as shown:
Oxidation at anode: $Zn\left(s\right)\to Z{n}^{2+}\left(aq\right)+2e^{-}$
Reduction at cathode: $C{u}^{2+}\left(aq\right)+2e^{-}\to Cu\left(s\right)$
