Other things being equal , the EMF of a Daniel cell may be increased by

Answer»

keeping low temperature
using large COPPER ELECTRODES
using large zinc electrodes
decreasing concentration of `Cu^(2+)` ions .

Solution :For Daniel cell ,
`ZN + Cu^(2+) to Zn^(2+) + Cu` ,
`E_("cell") = E_("cell")^(@) - (RT)/(nF) "ln" ([Zn^(2+)])/([Cu^(2+)])` .
Decrease of temperature and increase of `[Cu^(2+)]` will increase the EMF .
