Explain construction of Daniel cell. Write half cell reactions. How is Daniel cell symbollically represented?

Answer»

Solution :
At anode zinc gets oxidised. ELECTRONS flow through external CIRCUIT. At cathode `CU^(+2)` IONS get reduced.
At anode: `Zn to Zn^(+2)+2e^-`
At cathode: `Cu^(+2)+2e^(-) to Cu`
`Zn(s)|Zn^(+2) (aq) ||Cu^(+2) (aq) |Cu(s)`
(s and aq are not value points)
