Question

Calculate the EMF of a Danial cell when the concentration of $Z n S O_{4}$ and $C u S O_{4}$ are $0.001$ M and $0.1$ M respectively. The standard EMF of the cell is $1.1$ V.

Solution

Let
$E_{1} = E_{c e l l}^{0} - \frac{2.303 \times R T}{2 F} \times log \frac{(0.01)}{1}$
Therefore the concentration are changed,
$E_{2} = E_{c e l l}^{0} - \frac{2.303 R T}{2 F} \times \frac{(0.01)}{1}$
Hence,
$E_{1} > E_{2}$
