Problem

Consider the cell

\text{Ag} \mid \text{AgBr(s)} \mid \text{Br}^- \parallel \text{Cl}^- \mid \text{AgCl(s)} \mid \text{Ag}

25^\circ\text{C}

. The solubility product constants of AgBr & AgCl are respectively

5 \times 10^{-13}

1 \times 10^{-10}

. For what ratio of the concentrations of

\text{Br}^-

\text{Cl}^-

ions would the e.m.f. of the cell be zero? Report answer as

1000 \times

ratio.
