6) A voltaic cell is constructed with two silver chloride electrodes, where each of the half-reactions is: AgCl (s) + e? ? Ag (s) + Cl? (aq) EĀ° = +0.222 V The concentrations of chloride ions in the two compartments are 0.0100 M and 1.55 M, respectively. The cell emf is _______ V.

state the concept of EMF of a cell
Geeta Y.
A cell of emf $E$ is connected across a resistance $R$. The potential difference between the terminals of the cell is found to be $V$. The internal resistance of the cell must be (A) $\frac{2(E-V) V}{R}$ (B) $\frac{2(E-V) R}{E}$ (C) $\frac{(E-V) R}{V}$ (D) $(E-V) R$
The emf of the cell $\mathrm{Cu}(\mathrm{s})\left|\mathrm{Cu}^{2+}(\mathrm{aq}) \| \mathrm{Ag}^{+}(\mathrm{aq})\right| \mathrm{Ag}(\mathrm{s})$ $E^{\circ} \mathrm{Cu} / \mathrm{Cu}^{2+}=-0.34 \mathrm{~V} ; E^{\circ} \mathrm{Ag} / \mathrm{Ag}^{+}=-0.80 \mathrm{~V}$ (a) $+0.46 \mathrm{~V}$ (b) $-0.46 \mathrm{~V}$ (c) $+1.14 \mathrm{~V}$ (d) $-1.14 \mathrm{~V}$
