Question

Determine the potential of a Daniell cell, initially containing $1.00L$ each of $1.0M$ copper (II) ion and $1.0M$ zinc(II) ion, after passage of ${10}^5$ coulomb charge. The $E^{\circ }$ of the Daniell cell is $1.10volt$.

Answer 1

$1.09volt$.
By passage of ${10}^5$ coulomb charge, zinc ion concentration increases by $0.518mole$ while copper ion concentration decreases by $0.518mole$.
Thus, $\left[Z{n}^{2+}\right]=1.518M$ and $\left[C{u}^{2+}\right]=0.482M$.
