Question

which of the following will increase the voltage of the cell with following cell reaction?
`Sn(s)+2Ag^(+)+(aq)rarrSn^(+2)(aq)+2Ag(s)`
A. Increase in the size of silver rod
B. Increase in the conc. Of `Sn^(2+)` ions
C. Increase in the concentration of `Ag^(+)` ions
D. Increase in the concentration of `Ag^(+)` ions

Answer 1

Correct Answer - C
Since reduction occurs at Ag electrode. Hence increase in the conc. Of `Ag^(+)` or decrease in conc. Of `Sn^(2+)` wil increase the voltage.
