Which one of the following will increase the voltage of the cell ? `(T = 298 K)`
` Sn+ 2Ag^+ rarr Sn^(2+) +2 Ag`.

Options

A. increase in the size of silver rod
B. increase in the concentrationnnnn of `Sn^(+2)` ions
C. increase in the concentrationnnnn of `Ag^(+2)` ions
D. none of the above

Answer

C

Explanation

`E_(cell)=E_(cell)^@ -(0.059)/2 log .([Sn^(2+)])/([Ag^+]^2)`
` Ag^+` inceases, ` E_(cell)` increases.
